                           BEL REPORTS HIGHER REVENUE
                   AND NET EARNINGS FOR FIRST QUARTER OF 2004

         JERSEY CITY, NEW JERSEY, April 29, 2004 . . . BEL FUSE INC.
(NASDAQ:BELFA & NASDAQ:BELFB) today announced higher unaudited revenue and net
earnings for the first quarter of 2004.

         For the three months ended March 31, 2004, revenue increased 70% to
$42,357,000 from $24,947,000 for the first quarter of 2003. Gross margin
improved to 30% from 28% last year, and income from operations increased to
$5,615,000 from $2,133,000. Net earnings increased to $4,655,000, or $0.41 per
diluted share. This compares to net earnings of $1,780,000, or $0.16 per diluted
share, for the same period a year earlier.

         President Daniel Bernstein attributed the increase in first quarter
revenue primarily to the acquisition of the Passive Components Group from
Insilco Technologies, Inc. completed last spring. "The improvement in margins
primarily reflected efficiency enhancements associated with the integration of
the Passive Components Group and the introduction of new products. Bel's backlog
has increased in line with many companies in our industry, resulting in longer
lead times. This is an encouraging sign for the future," he said.

         At March 31, 2004, Bel had cash, cash equivalents and marketable
securities of approximately $70,400,000, working capital of approximately
$108,000,000, a current ratio of 6-to-1, total long-term debt of $6,000,000 and
shareholders' equity of approximately $152,000,000.
