HISTORICAL BACKGROUND:
Vishay Intertechnology was founded in 1962 by Dr. Felix Zandman to manufacture and commercialize precision Bulk Metal foil resistors, a technology developed from his research into stress measurement and high-stability resistance materials. Beginning in 1985, Vishay expanded through acquisitions of established resistor manufacturers, including Dale Electronics, Draloric, and Sfernice, later becoming a major international supplier of passive electronic components and semiconductors.

The Vishay Dale D/CRCW thick-film chip resistor family reflects the electronics industry's transition from traditional leaded resistors to compact surface-mount components. Thick-film technology uses a resistive material deposited onto a ceramic substrate and processed to achieve the required electrical resistance. Standardized 0603 packages became widely used in compact printed circuit boards, allowing automated assembly and high component density. The D/CRCW e3 family remains a widely distributed general-purpose surface-mount resistor series.
