New Vishay Intertechnology AEC-Q200 Qualified, Chassis-Mount Wirewound Resistors Offer High Reliability, Accuracy, and Stability for EVs

For Pre-Charge and Discharge Applications, Devices Combine a Robust Design With a Wide Resistance Range, Tight Tolerance Down to ± 1 %, and TCR Down to 20 ppm/°C

MALVERN, Pa., May 04, 2022 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of AEC-Q200 qualified, chassis-mount wirewound resistors targeted at the growing electric vehicle (EV) market.

Vishay Dale RHA series resistors mount directly onto a chassis to utilize the heat-sink effect. Offering high reliability, the devices feature a completely welded and molded construction for total environmental protection, and an operating temperature range of -55 °C to +250 °C. The resistors will serve as pre-charge and discharge resistors in EVs, in addition to voltage dividers in taillights and current limiters in dimming circuits for interior lighting.

The devices released today offer high power ratings up to 50 W in four small package sizes. The resistors’ tight tolerance down to ± 1 %, TCR as low as 20 ppm/°C, and wide resistance range from 0.1 kΩ to 39.2 kΩ enable higher accuracy and stability. The RHA series is RoHS-compliant, halogen-free, and Vishay Green.

Device Specification Table:

Part number	Power rating P25 (W)	Resistance range (Ω)	Dielectric withstanding voltage
RHA005	7.5	0.1 to 3.32 k	1000 VRMS
RHA010	12.5	0.1 to 5.62 k	1000 VRMS
RHA025	25	0.1 to 12.1 k	1000 VRMS
RHA050	50	0.1 to 39.2 k	2000 VRMS

Samples and production quantities of the RHA series are available now, with lead times of eight to 12 weeks.
