COVID-19 Update

Dear Valued Customer,

Subject: Coronavirus Update

Bel continues to monitor the situation, as it pertains to the Coronavirus (COVID19). We’ve implemented industry best practices throughout our facilities, including travel and visitor restrictions, work from home policies, social distancing, employee screenings, and regularly updating associates as to information posted by the Center for Disease Control and the World Health Organization. While fully supporting preparedness efforts by all applicable government entities, we realize that we also have a responsibility to our customers to maintain business continuity. All but one of our manufacturing facilities are currently operating. Signal Transformer’s factory in the Dominican Republic is currently limited to only supplying products that directly support the medical industry. We encourage all Signal customers to contact your local customer service representative to determine any specific impact. We will notify you should the situation change, due to the institution of any additional local, regional, or national regulations and guidelines. Bel’s other factories continue to operate at 8090% efficiency. In addition to working diligently to manage our own work force, we’re dealing with a global supply chain and logistics infrastructure, that remain areas of industrywide concern. We continue to work with each of our partners to get updated information, as timely as possible. We ask that you plan accordingly, as lead times on some materials are being extended 24 weeks.

I assure you that we remain fully committed to supporting each of our Bel, Cinch, CUI, Signal, Melcher and Stewart customers and, will do everything possible to provide you with timely updates as to the status of our global operations. Please work with your local Sales and Customer Service support teams concerning open orders and commit dates for specific part numbers. Contact information is available at www.belfuse.com

We will provide future updates as warranted.

Best Regards,Dan Bernstein President/CEO
