(NASDAQ:BELFA) and (NASDAQ:BELFB - News) today announced that it has issued a shareholder presentation and mailed a letter to the shareholders of Pulse Electronics Corporation (NYSE:PULS - News) in connection with Pulse's 2011 annual meeting of shareholders scheduled for May 18, 2011.

The full text of the letter follows:

VOTE YOUR GOLD PROXY CARD TODAY

May 3, 2011

Dear Pulse Electronics Shareholder:

DO NOT BE MISLED ABOUT THE FACTS

DEMAND ACCOUNTABILITY FROM THE PULSE BOARD

SEND A CLEAR MESSAGE THAT THE STATUS QUO IS NO LONGER ACCEPTABLE

The Board of Directors of Pulse Electronics has recently made statements regarding Bel's solicitation of proxies to elect two independent nominees to the Pulse Board at its upcoming annual meeting of shareholders that we believe are misleading and are intended to divert attention away from Pulse's poor performance and the clear benefits of combining both companies. In response, Bel has issued a shareholder presentation that seeks to address these statements and clarify why now is the right time for Pulse shareholders to act. You are encouraged to read the complete investor presentation, which is available at www.ProxyProcess.com/BelFuse.

Listed below are a few important points you should consider when voting the GOLD proxy card.

FACTS ABOUT BEL'S OFFER TO PURCHASE PULSE

· In 2006, representatives from Bel and Pulse began discussing a framework for a potential business combination

· On February 28, 2011, Bel publicly offered to purchase Pulse for $6.00 per share

· The Pulse Board summarily rejected Bel's proposal prior to making any attempt to engage with Bel to discuss a suitable valuation or transaction

· Both companies have agreed in the past that increasing raw material, labor and operating costs makes a Bel-Pulse combination very compelling for all shareholders

· Bel offered a significant premium for Pulse which is well above what analysts indicate Pulse is worth by itself

· Bel is willing to revise the offer price and the form of consideration to include cash and/or stock

· Bel is willing to collapse its A/B share structure if it makes the most sense for all shareholders

· Bel has the ability to finance and close the transaction quickly

YOUR LAST VOTE IS THE ONLY VOTE THAT COUNTS!

FACTS ABOUT THE ELECTION OF DIRECTORS

· In an attempt to urge the Pulse Board to examine ALL options available for maximizing shareholder value, Bel nominated two well-respected individuals for election to the Pulse Board at Pulse's 2011 annual meeting of shareholders

· After Bel made its offer and submitted its director nominations, Pulse expanded the Board from 6 to 8 members and nominated three new director candidates

· Pulse is NOT making radical changes to address their past governance and performance concerns. If all of Pulse's nominees are elected, the Board will continue to consist of 4 of 8 directors associated with Pulse's past performance problems

· Bel is NOT seeking control of the Pulse Board. If elected, Bel's candidates will hold just 2 of 8 board seats

· Bel is NOT seeking to surreptitiously obtain Pulse's intellectual property by planting spies on the Pulse Board. Bel's nominees will be bound by the same confidentiality restrictions and fiduciary duties as every other board member

· Bel's nominees are NOT "hand-picked" associates of Bel. These candidates are ethical, highly-qualified and completely independent from Bel. Both candidates were introduced to Bel through a specialized corporate governance consulting company and are well-respected advocates for shareholder rights

· Bel's nominees are NOT seeking to be disruptive inside the Pulse boardroom. If elected, these candidates will seek to work constructively with the other directors to ensure your value is protected

"One thing rings with absolute clarity in my mind: the combination of Bel and our ECS would be not just company altering but, more importantly, industry altering. For those shareholders who chose to stay with the company, it could be a very, very lucrative deal over the next decade and one which neither of us can provide all by ourselves, at least not in the mid term, and probably not ever. The economics of this deal are just so compelling and we owe it to our respective shareholders to do what we can to explore it carefully and, if possible, make it happen."

--- James Papada, former Pulse Chairman, in an email to Dan Bernstein, CEO of Bel, dated May 24, 2006, discussing a framework for a possible business combination
