Vishay Releases New 36 W Battery Shunt Resistor with Molded Enclosure
Press release date: November 21, 2012
Featuring High 36 W Power Capability and Low Resistance of 100 µΩ in 8518 Package Size
MALVERN, Pa. – Vishay Intertechnology, Inc. (NYSE: VSH) today announced a new Power Metal Strip® battery shunt resistor featuring a molded enclosure with a four-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 extremely 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 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 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="">
Samples and production quantities of the new battery shunt resistor are available now, with a lead time of 12 to 16 weeks for larger orders. Pricing for U.S. delivery only is $5.50 each in 10,000-piece quantities. Follow Power Metal Strip resistors at http://twitter.com/vishayindust.
