Vishay has announced a new Power Metal Strip battery shunt resistor that combines a 36-W power capability in the 8518 size package with extremely low resistance values down to 100 µΩ. The WSBS8518 battery shunt resistor features a proprietary processing technique that produces extremely low resistance values of 100 µΩ, 125 µΩ, and 250 µΩ. This provides increased accuracy in battery shunt applications for gas, diesel, hybrid, and electric cars, trucks, and scooters, as well as electric forklifts and other heavy industrial applications.
With a tolerance of 5.0 %, the new resistor provides more accurate data to determine battery charge and discharge, thus helping designers meet specific customer battery management requirements.

The WSBS8518 features an all-welded construction that allows operation with continuous currents as high as 600A. The resistor offers low inductance values of < 5 nH and a low thermal EMF of < 3 µV/°C. The device is lead (Pb)-free and RoHS-compliant.
