Vishay Draloric RCV e3 thick-film chip resistors

Vishay Intertechnology has released a 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 400 and 500 V in the compact 0805 and 1206 case sizes, respectively.

With their high voltages, the 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 400 and 500 V, respectively; power ratings of 0.125 and 0.25 W; insulation voltage >500 V; and high-temperature operation to +155°C. The devices offer tolerances of 1 and 5%; TCR of ±100 and ±200 ppm/K; and a resistance range from 100 kΩ to 10 MΩ.

The resistors feature a protective metal glaze layout suitable for high-voltage operation on high-quality ceramic, and pure tin solder contacts on a nickel barrier layer for compatibility with lead-free and lead-containing soldering processes. The devices are compliant to RoHS directive 2011/65/EU and halogen free according to the JEDEC JS709A definition.
