Vishay Intertechnology WSBS8518…40 Power Metal Strip® Battery Shunt Resistor Improves Accuracy, Provides Consistent Contact Location

Press release date: Jul 24, 2017

36 W Device Features Three Sense Pins to Assist in PCB Mounting, Offers Low Resistance Down to 50 µΩ

Vishay Intertechnology, Inc. (NYSE: VSH) today announced a new 36 W Power Metal Strip® battery shunt resistor featuring three sense pins in the 8518 case size. With extremely low resistance values down to 50 µΩ, the Vishay Dale WSBS8518...40 increases accuracy and lowers costs compared with Hall Effect current sensing solutions, while its sense pins assist in PCB mounting, provide consistent contact point location, and offer a connection to ground via the third sense pin.

The three sense pin device released today features a proprietary processing technique that produces extremely low resistance values of 50 µΩ, 100 µΩ, and 125 µΩ. These low values allow for more accurate data to determine battery charge and discharge, thus helping designers meet specific customer battery management requirements for applications in gas, diesel, hybrid, and electric cars and trucks, as well as electric forklifts, UPS systems, and other heavy industrial applications.

The WSBS8518...40 features a solid metal manganese-copper alloy resistive element with low TCR (± 20 ppm/°C) and a welded terminal to element connection that allows for up to 848 A of continuous current (value dependent). The resistor offers low inductance values of < 5 nH, low thermal EMF down to < 1 µV/°C, and an operating temperature range of -65 °C to +170 °C. The device is RoHS-compliant, halogen-free, and Vishay Green.

Samples and production quantities of the WSBS8518...40 are available now, with a lead time of 10 to 12 weeks for larger orders. Pricing for U.S. delivery only is $6.00 per piece in 100-piece quantities.
