Vishay Intertechnology has introduced the new WSBS8518…34 and WSBS8518…35 Power Metal Strip shunt resistors.
The devices feature a solid metal nickel-chrome alloy resistive element with a calibration notch and “boot” design on their terminals, which improves TCR performance (down to ± 10 ppm/°C) for better accuracy over temperature extremes.
With extremely low resistance down to 100 µΩ and power ratings to 36 W, the Vishay devices increase accuracy and lower costs compared with manganese alloy shunts and Hall Effect current sensing solutions, while the two sense pins of the WSBS8518…35 aid in PCB mounting and provide consistent contact point locations on the shunt.
Offered in the 8518 case size, the resistors feature a proprietary processing technique that produces their extremely low resistance values, which allow for high current capabilities.
The Key Application of the Power Metal Strip shunt resistors include:
The devices are designed for battery management in
- gas, diesel, hybrid, and electric cars and trucks
- electric forklifts
- large UPS systems
- heavy industrial applications.
Samples and production quantities of the WSBS8518…34 and WSBS8518…35 are available now, with a lead time of 10 to 12 weeks for larger orders.
