RCV-AT e3 Series: Thick Film Chip Resistors with High Voltage for On Board Chargers and EV Cars Inverters
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. The new RCV-AT e3 series can be used in place of standard resistor chains and 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. Moreover, these devices are suitable for processing on automatic surface-mount assembly systems, and wave, reflow, or vapor phase soldering per IEC 61760-1.
The RCV-AT e3 series features a resistance range from 100kΩ to 100MΩ, with tolerances of ± 1% and ± 5% and TCR of ± 100ppm/K and ± 200ppm/K. These resistors offer power ratings up to 1.0W, a low voltage coefficient of resistance of 25ppm/V, and an operating temperature range of -55°C to +155°C.
