Vishay unveils resistors with NiCr resistive element and a unique termination

Vishay Intertechnology, has unveiled the WSBS8518...34 and WSBS8518...35, two Power Metal Strip shunt resistors.

Designed with a solid metal nickel-chrome alloy resistive element with a calibration notch and "boot" design on their terminals, these resistors provide 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 Dale devices released 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 Vishay Green.

Samples and production quantities of the WSBS8518...34 and WSBS8518...35 are now available, with a lead time of 10 to 12 weeks for larger orders.
