I, Colin Dunn, certify that:

1.     I have reviewed this quarterly report on Form 10-Q of Bel Fuse,
       Inc.;

2.     Based on my knowledge, this report does not contain any untrue
       statement of a material fact or omit to state a material fact
       necessary to make the statements made, in light of the
       circumstances under which such statements were made, not
       misleading with respect to the period covered by this report;

3.     Based on my knowledge, the financial statements, and other
       financial information included in this report, fairly present in
       all material respects the financial condition, results of
       operations and cash flows of the registrant as of, and for, the
       periods presented in this report;

4.     The registrant's other certifying officers and I are responsible
       for establishing and maintaining disclosure controls and
       procedures (as defined in Exchange Act Rules 13a-15(e) and
       15d-15(e)) for the registrant and have:

            a. Designed such disclosure controls and procedures, or caused such
               disclosure controls and procedures to be designed under our
               supervision, to ensure that material information relating to the
               registrant, including its consolidated subsidiaries, is made
               known to us by others within those entities, particularly during
               the period in which this report is being prepared;

            b. Evaluated the effectiveness of the registrant's disclosure
               controls and procedures and presented in this report our
               conclusions about the effectiveness of the disclosure controls
               and procedures, as of the end of the period covered by this
               report based on such evaluation; and

            c. Disclosed in this report any change in the registrant's internal
               control over financial reporting that occurred during the
               registrant's most recent fiscal quarter (the registrant's fourth
               fiscal quarter in the case of an annual report) that has
               materially affected, or is reasonably likely to materially
               affect, the registrant's internal control over financial
               reporting; and

5.     The registrant's other certifying officer and I have disclosed,
       based on our most recent evaluation of internal control over
       financial reporting, to the registrant's auditors and the audit
       committee of the registrant's board of directors (or persons
       performing the equivalent functions):

            a. All significant deficiencies and material weaknesses in the
               design or operation of internal control over financial reporting
               which are reasonably likely to adversely affect the registrant's
               ability to record, process, summarize and report financial
               information; and

            b. Any fraud, whether or not material, that involves management or
               other employees who have a significant role in the registrant's
               internal control over financial reporting.
