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 have been released by Vishay Intertechnology. The Vishay Draloric RCV e3 devices offer high limiting element voltages of 400 and 500V in the compact 0805 and 1206 case sizes, respectively.
The high voltages allow the devices to 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 the RCV1206 e3 feature operating voltages of 400 and 500V, respectively; power ratings of 0.125 and 0.25W; insulation voltage greater than 500V; and high-temperature operation up to +155°C. The resistors offer tolerances of 1% and 5%, TCR of ±100ppm/K and ±200ppm/K, and a resistance range from 100kΩ to 10MΩ.
The RCV e3 devices 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 (Pb)-free and lead-containing soldering processes. The resistors are compliant to RoHS directive 2011/65/EU and halogen-free according to the JEDEC JS709A definition.
Samples and production quantities of the RCV e3 resistors are available now.
