Vishay's high-voltage chip resistors save board space and component count

Vishay Intertechnology has introduced a new series of AEC-Q200-qualified, thick-film chip resistors with operating voltages up to 3 kV in the 2010 and 2512 case sizes.

With their high-operating voltages, devices in the Vishay Draloric RCV-AT e3 series can be used in place of standard resistor chains.

This allows designers to save board space in inverters for electric (EV) and hybrid electric (HEV) vehicles, on-board chargers, and DC/DC converters while lowering component counts and reducing placement costs.

The RCV-AT e3 series features a resistance range from 100 k to 100 MΩ, with tolerances of ± 1 % and ± 5 % and TCR of ± 100 ppm/K and ± 200 ppm/K. The resistors offer power ratings up to 1.0 W, a low voltage coefficient of resistance of 25 ppm/V, and an operating temperature range of -55° to +155° C.

RoHS-compliant and halogen-free, the devices are suitable for processing on automatic surface-mount assembly systems, and wave, reflow, or vapor phase soldering per IEC 61760-1.
