                     Bel's Third Quarter Net Earnings Double
                                On 67% Sales Gain


         JERSEY CITY, NEW JERSEY, OCTOBER 29, 2003 ... BEL FUSE INC.
(NASDAQ:BELFA & NASDAQ:BELFB) announced today that net earnings for the third
quarter ended September 30, 2003 doubled to $3,630,000, or $0.32 per diluted
share, from $1,746,000, or $0.16 per diluted share, for the third quarter of
2002. Revenue increased 67% to $45,864,000 compared to $27,401,000 for the same
period last year.

         For the nine months ended September 30, 2003, net earnings increased to
$8,167,000, or $0.73 per diluted share. This compares to net earnings of
$1,218,000, or $0.11 per diluted share, for the first nine months of 2002. Sales
increased 68% to $115,632,000 from $68,642,000 for the same period a year
earlier.

         Daniel Bernstein, President, said, "Our strong sales gains largely
reflect the acquisition, last Spring, of the Passive Components Group from
Insilco Technologies. Profitability has benefited from operating improvements at
the Passive Components Group and the introduction of new products, particularly
our expanding line of integrated connector modules. Consequently, Bel's third
quarter gross margin improved to 29% of sales compared to 23% for the third
quarter last year, and income from operations increased to 12% of sales from 7%
of sales in the third quarter last year."

         At September 30, 2003, Bel reported cash, cash equivalents and
marketable securities of approximately $52,000,000, working capital of
approximately $93,700,000, a current ratio of 5.3-to-1, total term debt of
$7,000,000 and shareholders' equity of approximately $140,300,000, or $12.63 per
share.
