The Beyschlag name stands for thin film technology, continuous innovation, excellence in service and logistics, and customer-oriented solutions. Beyschlag, founded as a company in 1931, grew to become the leading European manufacturer of metal film resistors. Beyschlag innovations include cylindrical metal film SMD resistors (MELF resistors), Mini-MELF resistors, and thin film flat chip resistors. Beyschlag became part of Philips Components in 1974. Subsequently, in January 1999, BCcomponents (Beyschlag Centralab components) emerged from Philips Electronics as a leading manufacturer of passive electronic components. Beyschlag, as part of BCcomponents, earned the status of preferred supplier to many of the world's leading electronics companies.

Vishay acquired BCcomponents in December 2002. The former BCcomponents product portfolio is now divided into Vishay Beyschlag and Vishay BCcomponents. Products branded Vishay Beyschlag include carbon film MELF resistors, Cermet film chip resistors, leaded carbon film resistors, leaded metal film resistors, thin film chip resistors, thin film chip resistor arrays, and thin film MELF resistors.
