                        BEL REITERATES PROPOSAL TO MERGE
                            WITH ARTESYN TECHNOLOGIES


           JERSEY CITY, N.J. -- September 23, 2004 -- BEL FUSE INC.
      (NASDAQ:BELFA & NASDAQ:BELFB) announced today that it remains committed to
      pursuing a possible acquisition of Artesyn Technologies, Inc. and
      reiterated its proposal for a stock for stock merger in which Bel would
      issue 0.265 shares of its Class B common stock for each share of Artesyn
      stock.

           Daniel Bernstein, President and Chief Executive Officer of Bel,
      stated "I am extremely disappointed that Artesyn's board has declined all
      of our offers to meet and review our proposal. It is not at all obvious to
      me or our board how Artesyn can determine the adequacy of our proposal
      when we have not yet had a chance to discuss our strategic plan and the
      benefits we see in a combination."

           Mr. Bernstein added, "We continue to believe that our merger proposal
      represents a sound and compelling proposition for both sets of
      shareholders. As we stated in our August 31, 2004 letter to Artesyn, we
      believe that the proposed strategic combination of Artesyn and Bel would
      create one of the strongest electro-mechanical vendors in the world,
      supplying a broad array of components and subsystems to most of the
      leading computing, networking and telecommunications companies around the
      globe. In our view, Artesyn shareholders would not only receive a
      significant premium over the share price in effect prior to our previously
      announced purchases of Artesyn common stock, but they would also maintain
      ownership in a company which we believe would have a significantly greater
      opportunity for growth and stock price appreciation going forward."

           Mr. Bernstein noted that while Artesyn's stock has underperformed
      most of the major indices, including the S&P 500 and the NASDAQ Composite
      Index, over the past five years, Bel's stock has outperformed these
      indices and has appreciated by more than 140% during the same time period.
      For the two and a half years ended June 30, 2004, Bel's cumulative net
      earnings amounted to $26,243,000, while Artesyn lost $119,449,000. In
      addition, Bel's total shareholders' equity at the end of the most recent
      quarter was approximately one third larger than Artesyn's.

           Mr. Bernstein concluded that Bel remains willing to entertain
      negotiations with Artesyn regarding a transaction and would welcome the
      opportunity to consider non-public information about Artesyn in order to
      determine if any enhanced values might be demonstrated by such
      information.

           Bel will discuss this press release during a conference call at 4:15
      p.m. EDT on Monday, September 27, 2004. You can dial-in for the live call
      at (212) 896-6010, reservation #21209487. The live call can be accessed
