New Vishay Intertechnology AEC-Q200 Qualified Hybrid Wirewound Charging Resistor Lowers Component Counts and Costs in EVs, HEVs, and PHEVs
Vishay Intertechnology has launched a new AEC-Q200 qualified charging resistor, the HRHA, notable for its hybrid wirewound technology. This resistor delivers 10 times higher energy absorption compared to traditional components of the same size, making it suitable for electric and hybrid vehicles. It operates at temperatures up to +250 °C and has power ratings of up to 90 W. The HRHA simplifies design requirements, allowing a single component to replace multiple resistors, potentially lowering overall solution costs. Samples and production quantities are currently available.
- Launch of HRHA charging resistor with hybrid wirewound technology.

- High power ratings (90 W on stainless steel, 54 W on Pamitherm).
- Temperature tolerance up to +250 °C, enhancing vehicle performance.
- Simplifies design by reducing component count, potentially lowering costs.
- None.
For Pre-Charge and Discharge Applications, Device Delivers 10x Higher Energy Absorption Than Other Component Technologies in the Same Size
MALVERN, Pa., March 16, 2022 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new AEC-Q200 qualified charging resistor that is the industry’s first such device to feature hybrid wirewound technology in a standard package size.
With a high operating temperature range up to +250 °C, the Vishay MCB HRHA will serve as a pre-charge and discharge resistor in inverters and converters for electric (EV), hybrid electric (HEV), and plug-in hybrid vehicles (PHEV). Typically, designers must utilize several thick film resistors to meet the high pulse requirements of these applications. With 10 times the energy absorption in the same size (i.e., 6 kJ for 300 ms), the HRHA allows them to use a single component and lower overall solution costs.
The device released today offers high power ratings up to 90 W on stainless steel and 54 W on Pamitherm. For high accuracy and stability, the resistor features tolerance down to ± 5 %, TCR down to ± 100 ppm/°C, and a resistance range from 1 Ω to 1 k Ω. Easy to mount, the HRHA features a 6.35 mm faston connection. The device can be mounted on a heatsink and is available with an optional integrated fuse.
Samples and production quantities of the HRHA series are available now, with lead times of eight to 12 weeks.
