               AMERICAN TECHNICAL CERAMICS CORP. AND SUBSIDIARIES

              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS



(1)      PRINCIPLES OF CONSOLIDATION:

         The accompanying unaudited interim consolidated financial statements
of American Technical Ceramics Corp. and Subsidiaries (the "Registrant")
reflect all adjustments (consisting of normal recurring accruals) which are, in
the opinion of management, necessary for a fair presentation of its
consolidated financial position as of December 31, 1997 and the results of its
operations for the quarter and six months ended December 31, 1997 and 1996.
These financial statements should be read in conjunction with the summary of
significant accounting policies and notes to consolidated financial statements
included in the Registrant's Annual Report to Stockholders for the year ended
June 30, 1997. Results for the six months ended December 31, 1997 are not
necessarily indicative of results which could be expected for the entire year.


(2)      INVENTORIES:

         Inventories included in the accompanying consolidated financial
statements consist of the following:

                                         Dec. 31,          June 30,

(3)      EARNINGS PER SHARE:

         Statement of Financial Accounting Standards No. 128 Earnings Per Share
("SFAS No. 128") establishes new standards for computing and presenting
earnings per share ("EPS") and applies to all entities with publicly held
common stock. SFAS No. 128 replaces the presentation of primary EPS with a
presentation of basic EPS and requires a dual presentation of basic and diluted
EPS on the face of the income statement for all entities with complex capital
structures and requires a

reconciliation of the numerators and denominators of the basic and diluted EPS
computations. This Statement is effective for financial statements issued for
periods ending after December 15, 1997. The Registrant has adopted SFAS No. 128
and therefore has calculated current periods' EPS in accordance with this new
standard. Accordingly, all prior periods' EPS data have been restated to
furnish comparative information.

ITEM 2.        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS


         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, fluctuations in operating results and delays in
development of highly complex products and the other matters listed in the
Registrant's Annual Report on Form 10-K for the fiscal year ended June 30, 1997

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

Three Months Ended December 31, 1997
Compared with Three Months Ended December 31, 1996
--------------------------------------------------

         Net sales for the three months ended December 31, 1997 increased 25%
to $10,822,000 as compared to net sales of $8,637,000 for the comparable
quarter in the prior fiscal year. This increase was primarily the result of a
significant increase in demand for commercial products in both domestic and
foreign markets. The backlog of unfilled orders was $7,552,000 at December 31,
1997 compared to $7,356,000 at December 31, 1996 and $7,721,000 at June 30,
1997.

RESULTS OF OPERATIONS, continued
--------------------------------


         Gross margin for the three months ended December 31, 1997 was 46.2% of
net sales as compared to 39.1% for the comparable quarter in the prior fiscal
year. The higher gross margin in the current quarter was primarily attributable
to production efficiencies afforded by higher sales levels, as well as a
product mix with a greater proportion of higher-margin products than has been
experienced in recent quarters. The Registrant believes product mix will
continue to vary from quarter to quarter. It is difficult to predict what
impact these variations will have on the Registrant's gross margins in the
future. The improvement in gross margin also reflects process improvements
which had not been fully implemented during the second quarter of fiscal 
year 1997.

         Total operating expenses for the three months ended December 31, 1997
increased 21% to $2,670,000 as compared to $2,212,000 in the comparable period
in the prior fiscal year. Selling, general and administrative expenses for the
three months ended December 31, 1997 increased 18% to $2,229,000 as compared to
$1,888,000 in the comparable period in the prior fiscal year, primarily as a
result of the higher levels of sales. Increased selling expenses included
higher salaries, commissions to representatives and expenses relating to
advertising and promotion activities. The increase in general and
administrative expense is attributable to higher salaries and bonus accruals
due to higher pretax profits.

     Research and development expenses for the three months ended December 31,
1997 increased 36% to $441,000 as compared to $324,000 in the comparable period
in the prior year. The increase in research and development expenses was
primarily the result of higher salary expense due to an increase in research
and development personnel. The Registrant expects that expenditures for
research and development will continue at least at current levels throughout
the remainder of fiscal year 1998.

     As a result of the foregoing, net income for the three months ended
December 31, 1997 was $1,517,000, or $.39 per common share ($.38 per common
share assuming dilution), compared to net income of $717,000, or $.18 per
common share ($.18 per common share assuming dilution), for the comparable
period in the prior fiscal year.

Six Months Ended December 31, 1997
Compared with Six Months Ended December 31, 1996
------------------------------------------------

         Net sales for the six months ended December 31, 1997 increased 23% to
$20,780,000 as compared to net sales of $16,926,000 for the comparable period
in the prior fiscal year. The increased sales was primarily the result of a
significant increase in demand for commercial products in both domestic and
foreign markets.

         Gross margin for the six months ended December 31, 1997 was 43.5% of
net sales as compared to 34.3% for the comparable period in the prior fiscal
year. The higher gross margin in the current period was primarily attributable
to production efficiencies afforded by higher sales levels, product mix with
a greater proportion of higher-margin products than has been experienced in 
recent quarters, and the full effects of process improvements which were not
fully implemented during the six months ended December 31, 1996. 

         Total operating expenses for the six months ended December 31, 1997
increased 24% to $5,057,000 as compared to $4,074,000 in the comparable period
in the prior fiscal year. Selling, general administrative expenses for the six
months ended December 31, 1997 increased 25% to $4,227,000 as compared to
$3,377,000 in the comparable period in the prior fiscal year, primarily as a
result of the higher levels of sales. Increased selling expenses included
higher salaries, higher commissions to representatives and expenses relating 
to advertising and promotion activities. The increase in general and
administrative expenses is attributable to higher salaries and bonus accruals
due to higher pretax profits.

         Research and development expenses for the six months ended December
31, 1997 increased 19% to $830,000 as compared to $697,000 in the comparable
period in the prior year. The increase in research and development expenses was
primarily the result of higher salary expense due to an increase in research
and development personnel.

         As a result of the foregoing, net income amounted to $2,561,000, or
approximately $.66 per common share ($.63 per common share assuming dilution),
for the six months ended December 31, 1997 compared to net income of
$1,052,000, or approximately $.27 per common share ($.27 per common share
assuming dilution) for the comparable period in the prior fiscal year.

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

         The Registrant's financial position at December 31, 1997 remains
strong as evidenced by working capital of $18,013,000 and stockholders' equity
of $29,292,000. The Registrant's current ratio at December 31, 1997 was 4.1:1
as compared to a current ratio of 4.2:1 at June 30, 1997. The Registrant's
quick ratio at December 31, 1997 was 2.6:1 as compared to a quick ratio of
2.4:1 at June 30, 1997.

         Cash and investments increased by $2,036,000 to $8,993,000 at December
31, 1997 from $6,957,000 at June 30, 1997 primarily as a result of the increase
in net income. Accounts receivable increased by $244,000 to $4,764,000 at
December 31, 1997 from $4,520,000 at June 30, 1997. Inventories decreased by
$47,000 to $8,980,000 at December 31, 1997 from $9,027,000 at June 30, 1997.
Accounts payable and accrued expenses increased by $206,000 to $3,901,000 at
December 31, 1997 from $3,695,000 at June 30, 1997, primarily as a result of
increased expenses related to the higher levels of sales. Income taxes paid in
the six month period ended December 31, 1997 were $1,088,000.

         In September 1996, the Registrant secured a $2,000,000 revolving
line-of-credit from Barnett Bank of Jacksonville, N.A. ("Barnett"). The
line-of-credit is subject to certain fees on the unused portion while the
outstanding balance bears interest at a rate equal to Barnett's prime rate
minus one-half percent (1/2%). Borrowings under the line-of-credit are subject
to, among other things, continued compliance with certain financial covenants,
including maintenance of asset and liability percentage ratios. There is
currently no balance outstanding under this line-of-credit.

         Capital expenditures for the six months ended December 31, 1997
totaled $1,460,000 of which $1,054,000 was for machinery and equipment. The
Registrant intends to use cash on hand and funds generated from operations to
finance additional budgeted capital expenditures of approximately $1.5 million
in fiscal year 1998, primarily for additions to and replacement of machinery
and equipment.

         In June 1990, the Registrant announced a stock purchase program
pursuant to which it is authorized to purchase up to $1,000,000 of its Common
Stock. As of December 31, 1997, the Registrant has expended approximately
$805,000 to purchase an aggregate of 308,400 shares under this program.
