Vishay Intertechnology WSBS Power Metal Strip® Shunt Resistors With NiCr Resistive Element and Unique Termination Design Increase Accuracy With Improved RTC Performance
Available With Two Sense Pins, Devices Feature Low Resistance Down to 100 µΩ and Power Rating to 36 W
MALVERN, Pa., April 11, 2019 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced the new and Power Metal Strip® shunt resistors with a solid metal nickel-chrome alloy resistive element with a calibration notch and “boot” design on their terminals, which improves TCR performance (down to ± 10 ppm/°C) for better accuracy over temperature extremes.
With extremely low resistance down to 100 µΩ and power ratings to 36 W, the Vishay Dale devices released today increase accuracy and lower costs compared with manganese alloy shunts and Hall Effect current sensing solutions, while the two sense pins of the WSBS8518...35 aid in PCB mounting and provide consistent contact point locations on the shunt.
Offered in the 8518 case size, the resistors feature a proprietary processing technique that produces their extremely low resistance values, which allow for high current capabilities. The devices are designed for battery management in gas, diesel, hybrid, and electric cars and trucks, as well as electric forklifts, large UPS systems, and other heavy industrial applications.
Featuring an all-welded construction, the WSBS8518...34 and WSBS8518...35 offer low inductance values of < 5 nH, low thermal EMF down to < 1.25 µV/°C, and an operating temperature range of -65 °C to +170 °C. The resistors are RoHS-compliant, halogen-free, and .
Samples and production quantities of the WSBS8518...34 and WSBS8518...35 are available now, with a lead time of 10 to 12 weeks for larger orders.
