Vishay Intertechnology, Inc. today released a new series of thick-film chip resistors designed to meet the demand for high voltages in industrial and medical applications while saving valuable PCB space. Vishay Draloric RCV e3 devices offer high limiting element voltages of 400V and 500V in the compact 0805 and 1206 case sizes, respectively.

With their high voltages, RCV e3 series resistors can replace multiple standard devices of the same size to save placement cost and board space in power supplies, battery chargers, vacuum tubes, and converters. The RCV0805 e3 and RCV1206 e3 feature operating voltages of 400V and 500V, respectively; power ratings of 0.125W and 0.25W; insulation voltage greater than 500V; and high-temperature operation to +155 degrees C. The devices offer tolerances of 1% and 5%, TCR of ± 100 ppm/K and ± 200 ppm/K, and a resistance range from 100kΩ to 10MΩ.
