ITEM 2.         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS
                      (In thousands, except per share data)

         The following discussion and analysis should be read in conjunction
with the consolidated financial statements, related notes and other information
included in this Quarterly Report on Form 10-Q.

         Statements in this Quarterly Report on Form 10-Q that are not
historical fact may constitute "forward-looking statements" within the meaning
of the Private Securities Litigation Reform Act of 1995. All such
forward-looking statements are subject to risks and uncertainties, including,
but not limited to, the impact of competitive products, product demand and
market acceptance risks, changes in product mix, costs and availability of raw
materials, fluctuations in operating results and delays in development of highly
complex products, risks associated with international sales and sales to the U.
S. military, risk of customer contract or sales order cancellation and the other
matters listed in the Registrant's Annual Report on Form 10-K for the fiscal
year ended June 30, 1999 under the caption "Item 1. Business - Cautionary
Statements Regarding Forward-Looking Statements" and in the Registrant's other
filings with the Securities and Exchange Commission. These risks could cause the
Registrant's actual results for future periods to differ materially from those
expressed in any forward-looking statements made by the Registrant.


RESULTS OF OPERATIONS
---------------------

Three Months Ended March 31, 2000
Compared with Three Months Ended March 31, 1999
-----------------------------------------------

         Net sales for the three months ended March 31, 2000 increased by 85% to
$18,424, from $9,954 in the comparable quarter in the prior fiscal year. The
increase in net sales was attributable to increases in virtually all product
areas, with the strongest growth in thin film products and core domestic
capacitors. Sales activity continued at similar rates during the first month of
the fourth quarter and the Registrant expects to sustain the current level of
business for the balance of the fiscal year. Sales to a major telecommunications
OEM accounted for 19% of the Registrant's net sales in the three months ended
March 31, 2000.

         The backlog of unfilled orders was $18,965 at March 31, 2000, compared
to $10,014 at March 31, 1999 and $14,836 at December 31, 1999. The increase in
backlog compared to both the comparable quarter in the prior fiscal year and the
immediately preceding quarter was due primarily to the continued strong demand
for the Registrant's products.

         Gross margin for the three months ended March 31, 2000 was 51% of net
sales as compared to 43% for the comparable period in the prior fiscal year. The
improvement in gross margin reported in the three months ended March 31, 2000 as
compared to the comparable period in the prior fiscal year was principally due
to the higher sales volume, particularly in thin film products, and the
resulting increases in efficiency.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                 CONDITION AND RESULTS OF OPERATIONS (CONTINUED)
                      (In thousands, except per share data)


         In February 2000, the Registrant commenced purchasing palladium, which
is used in the manufacturing of the majority of the Registrant's capacitors,
after not having done so for approximately 12 months. Prevailing market prices
for palladium are significantly higher than prices the Registrant paid for
palladium held in inventory at March 31, 2000. The Registrant has offset the
increased costs of this material in part by increasing the prices of certain of
its products that utilize large amounts of this material relative to their sales
prices. The Registrant's newer products are being designed to minimize or
eliminate the usage of palladium. At its current usage rate, the Registrant
expects that, to the extent that it is not able to reflect increases in the
market price of palladium in the prices of its products, these higher material
prices may negatively impact gross margins in the latter half of fiscal year
2001.

         Selling, general and administrative expenses for the three months ended
March 31, 2000 increased 64% to $3,675 as compared to $2,246 in the comparable
period in the prior fiscal year. The increase was due to increased commissions
as a result of the increase in net sales, an increase in bonus expense as a
result of the increase in net income, a new executive incentive plan and
expenses associated with the Registrant's new sales office in Stockholm, Sweden,
which commenced operations in August 1999.

         Research and development expenses for the three months ended March 31,
2000 increased 43% to $722 as compared to $506 in the comparable period in the
prior fiscal year. This increase was primarily the result of increased personnel
costs due to the creation of a dedicated Radio Frequency design group. This
group works with the Registrant's existing design and marketing personnel in
order to accelerate the development of new products and increase the breadth of
the Registrant's research and development activities.

         Primarily as a result of the foregoing, net income for the three months
ended March 31, 2000 was $3,202, or $0.83 per common share ($0.78 per common
share assuming dilution), compared to net income of $966, or $0.25 per common
share ($0.25 per common share assuming dilution), for the comparable period in
the prior fiscal year.

Nine Months Ended March 31, 2000
Compared with Nine Months Ended March 31, 1999
----------------------------------------------

         Net sales for the nine months ended March 31, 2000 increased 67% to
$45,180 as compared to net sales of $27,097 for the comparable period in the
prior fiscal year. The increase in sales was primarily the result of an increase
in overall demand for thin film and core domestic commercial capacitors. Sales
to a major telecommunications OEM accounted for 16% of the Registrants net sales
in the nine months ended March 31, 2000.

         Gross margin for the nine months ended March 31, 2000 was 44% of net
sales as compared to 36% for the comparable period in the prior fiscal year. The
improvement in gross margin was primarily due to higher sales volume,
particularly in thin film products, and the resulting increases in efficiency.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                 CONDITION AND RESULTS OF OPERATIONS (CONTINUED)
                      (In thousands, except per share data)


         Selling, general and administrative expenses for the nine months ended
March 31, 2000 increased 41% to $8,908 as compared to $6,305 in the comparable
period in the prior fiscal year, primarily due to increased commissions as a
result of the increase in net sales, an increase in bonus expense as a result of
increase in net income, a new executive incentive plan and expenses associated
with the Registrant's sales office in Stockholm, Sweden, which commenced
operations in August 1999.

         Research and development expenses for the nine months ended March 31,
2000 increased 37% to $1,970 as compared to $1,442 in the comparable period in
the prior year. This increase was primarily the result of increased personnel
costs due to the creation of the dedicated Radio Frequency design group and
general increases in recruitment and relocation expenses.

         As a result of the foregoing, net income amounted to $5,691, or
approximately $1.48 per common share ($1.42 per common share assuming dilution),
for the nine months ended March 31, 2000 compared to net income of $1,400, or
approximately $0.36 per common share ($0.36 per common share assuming dilution),
for the comparable period in the prior fiscal year.

LIQUIDITY AND CAPITAL RESOURCES
-------------------------------

         The Registrant's financial position at March 31, 2000 remains strong as
evidenced by working capital of $23,391 and stockholders' equity of $38,432. The
Registrant's current ratio at March 31, 2000 was 3.4:1 as compared to a current
ratio of 4.5:1 at June 30, 1999. The Registrant's quick ratio at March 31, 2000
was 1.9:1 compared to the quick ratio at June 30, 1999 of 2.2:1.

         Cash and investments increased by $1,394 to $7,421 at March 31, 2000
from $6,027 at June 30, 1999, primarily as a result of increased cash flow from
profitable operations. Accounts receivable increased by 83% to $9,662 at March
31, 2000 from $5,274 at June 30, 1999 due to the higher level of sales.
Inventories increased by 15% to $14,281 at March 31, 2000 from $12,436 at June
30, 1999, primarily due to an increase in work in process to support the
increased level of sales. Accounts payable and accrued expenses increased by 81%
to $7,592 at March 31, 2000 from $4,192 at June 30, 1999, primarily as a result
of increased raw material purchases and increased bonus and commission expense.
Income taxes paid in the nine month period ended March 31, 2000 were $1,886.

         In November 1998, the Registrant renewed a $2,000 revolving
line-of-credit with NationsBank, NA ("NationsBank"), the successor to Barnett
Bank of Jacksonville, N.A. ("Barnett Bank"), and secured a $3,500 line-of-credit
with NationsBank for equipment purchases. Both lines bear interest at 2% above
the three month rate for U. S. Dollar deposits on the London Interbank Market.
Principal balances under the revolving line-of-credit will be repayable in eight
quarterly installments commencing upon expiration of the revolving period. The
outstanding principal under the equipment line of credit will be rolled over
periodically into a self amortizing term note of not less than four nor more
than seven years. The equipment loan is secured by the related equipment
purchases. Borrowing under both lines is subject to compliance with certain
financial covenants, including maintenance of asset and liability percentage
ratios. As of March 31, 2000, the Registrant has borrowed an aggregate of $796
under the equipment line.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                 CONDITION AND RESULTS OF OPERATIONS (CONTINUED)
                        (In thousands except share data)


         In April 2000, the Registrant amended its loan agreement with Bank of
America, N.A. ("Bank of America"), the successor to NationsBank, N.A. The
amendment increased the revolving line-of-credit to $4,000 and changed the
interest rate. Both lines now bear interest at 1 1/2 % above the one month rate
for U.S. Dollar deposits on the London Interbank Market. All other terms and
conditions of the loan agreement are substantially the same as those contained
in the original agreement entered into during November 1998. At the same time,
the outstanding principal balance under the equipment line of credit was rolled
over into a seven-year term note. Principal on this note is payable in quarterly
installments of $28, commencing July 1, 2000.

         Capital expenditures for the nine months ended March 31, 2000 totaled
$4,161 of which $3,107 was for machinery and equipment. The Registrant intends
to use cash on hand and its equipment line of credit to finance budgeted capital
expenditures of approximately $2,300 for the remainder of fiscal year 2000,
primarily for additions to and replacement of machinery and equipment,
replacement of the information technology systems and facility expansion.

YEAR 2000
---------
         The Registrant had previously completed all remediation and testing of
internal computer systems that it believed could have been affected by the "Year
2000" problem, and has not incurred any problems with the "Year 2000" problem to
date. The Registrant did not incur, nor does it expect to incur, significant
incremental expenditures related to its Year 2000 activities.

ACCOUNTING STANDARDS ISSUED BUT NOT YET ADOPTED
-----------------------------------------------

         In fiscal year 2001, the Registrant will be required to adopt SFAS No.
133, "Accounting for Derivative Instruments and Hedging Activities." The
Registrant has not yet completed its evaluation of the impact of this statement
on its financial statements.

         FASB Interpretation No. 44, "Accounting for Certain Transactions
Involving Stock Compensation" ("FIN No. 44") provides guidance for applying APB
Opinion No. 25, "Accounting for Stock Issued to Employees." With certain
exceptions, FIN No. 44 applies prospectively to new awards, exchanges of awards
in a business combination, modifications to outstanding awards and changes in
grantee status on or after July 1, 2000. The Registrant does not believe that
the implementation of FIN No. 44 will have a significant effect on its results
of operations.

         In December 1999, the SEC issued Staff Accounting Bulletin No. 101,
"Revenue Recognition in Financial Statements" ("SAB No. 101") which summarizes
certain of the SEC staff's views in applying generally accepted accounting
principles to revenue recognition in financial statements. The Registrant will
be required to adopt the accounting provisions of SAB No. 101 during fiscal year
2001. The Registrant does not believe that the implementation of SAB No. 101
will have a significant effect on its results of operations.
