Keywords:Chip resistor 

Vishay Intertechnology rolled out the Draloric RCV e3 thick film chip resistors optimised for high voltages in industrial and medical applications. The halogen-free devices offer limiting element voltages of 400V and 500V in compact 0805 and 1206 case sizes, respectively.

The 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 > 500V; and high-temperature operation to 155°C.

Vishay Draloric RCV e3

The devices offer tolerances of 1 per cent and 5 per cent, TCR of ±100ppm/K and ±200ppm/K, and a resistance range from 100kΩ to 10MΩ.

The RCV e3 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 (Pb)-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.

Samples and production quantities of the RCV e3 resistors are available now, with lead times of eight weeks for larger orders.
