Vishay Intertechnology has 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, using 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° 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 new wirewound resistors offer high power ratings of up to 50 W in four small package sizes. The resistors’ tight tolerance is down to ± 1 %, the TCR is as low as 20 ppm/°C, and they offer a wide resistance range between 0.1 k to 39.2 kΩ, enabling higher accuracy and stability.
The RHA series is RoHS-compliant, halogen-free, and Vishay Green.
