A new series of AEC-Q200 qualified thick-film chip resistors, with operating voltages up to 3 kV and in the 2010 and 2512 case sizes, has been introduced by Vishay. 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 kΩ 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 W, a low voltage coefficient of resistance of 25 ppm/V and an operating temperature range of -55°C to +155°C.
RoHS-compliant and halogen-free, the devices are suitable for processing on automatic surface-mount assembly systems and for wave, reflow or vapour phase soldering per IEC 61760-1.
