Providing easy PCB connection to the shunt resistor assembly, the device allows design engineers to focus on circuit development instead of PCB connection issues.

Built using proprietary processing techniques, the WSBM8518 combines a high 36W power capability in the 8518 package size with extremely low resistance of 100µΩ. 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 new resistor provides more accurate data to determine battery charge and discharge, thus helping designers meet specific customer battery-management requirements. Its molded enclosure simplifies designs to reduce overall solution costs.

The WSBM8518 features an all-welded construction that allows operation with continuous currents as high as 600A. The resistor offers low inductance values of under 5 nH and a low thermal EMF of less than 3µV/°C. The device is lead (Pb)-free and RoHS-compliant.
