Battery Shunt Resistors Increase Accuracy, Lower Costs

Vishay Intertechnology’s WSBS5216 and WSBS5216...14 12W Power Metal Strip battery shunt resistors come in a 5216 case size and offer a resistance value of 100 µΩ. The AEC-Q200 qualified components promise to 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 resistors employ 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.

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 is $1.95 each/1,000. For greater knowledge, peruse the WSBS5216 and WSBS5216...14 datasheets.
