Technitrol has sent a letter to Bel Fuse offering to acquire the company for $40.30 per share, or $480 million, in cash. Technitrol would finance the transaction with cash on hand and debt. The company also offered to provide part of the consideration in Technitrol stock, should Bel Fuse so desire. Technitrol is a producer of electronic components, electrical contacts and assemblies and other precision-engineered parts and materials. Bel Fuse is a manufacturer and supplier of magnetics-based components and modules, interconnect products and circuit protection devices. Its product lines strongly complement those of Technitrol's Electronic Components Group in several markets, including networking, telecommunications and automotive. Bel Fuse refused to discuss these offers.
