Vishay Intertechnology WSBM8518 Power Metal Strip battery shunt resistor

Vishay Intertechnology’s Power Metal Strip battery shunt resistor features a moulded enclosure with a 4-pin connector. Providing easy PCB connection to the shunt resistor assembly, the WSBM8518 allows design engineers to focus on circuit development instead of PCB connection issues.

Built using proprietary processing techniques, the WSBM8518 combines a high 36 W power capability in the 8518 package size with low resistance of 100 µΩ. This provides increased accuracy in battery shunt applications for gas, diesel, hybrid and electric cars and trucks, as well as electric forklifts, utility trucks and other heavy industrial applications.

With a tolerance of 5.0%, the resistor provides more accurate data to determine battery charge and discharge, thus helping designers meet specific customer battery-management requirements. Its moulded enclosure simplifies designs to reduce overall solution costs.

The WSBM8518 features an all-welded construction that allows operation with continuous currents as high as 600 A. 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.
