Original Press Release:

Vishay Intertechnology WSBS Power Metal Strip® Battery Shunt Resistors in 5216 Size Increase Accuracy, Lower Costs and Provide Improved Corrosion Protection

12 W Devices Available With Optional Sn Plating to Assist in PCB Mounting, Offer Low Resistance of 100 µΩ

Malvern, Pa. — Feb. 11, 2019  Vishay Intertechnology, Inc. (NYSE: VSH) today introduced the new WSBS5216 and WSBS5216...14 12 W Power Metal Strip® battery shunt resistors in the compact 5216 case size. With extremely low resistance of 100 µΩ, the Vishay Dale AEC-Q200 qualified devices increase accuracy and lower costs compared with Hall Effect current sensing solutions, while the optional Sn terminal plating of the WSBS5216...14 assists with PCB mounting and provides improved corrosion protection.

The devices released today feature a proprietary processing technique that produces their extremely low resistance value. This low value allows 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 WSBS5216 and WSBS5216...14 feature 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 346 A of continuous current. The resistors offer 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 devices are RoHS-compliant, halogen-free, and Vishay Green.

Samples and production quantities of the WSBS5216 and WSBS5216...14 are available now, with a lead time of eight to 10 weeks for larger orders. Pricing for U.S. delivery only is $1.95 per piece in 1000-piece quantities.
