Vishay’s WSLP power metal strip current sensing resistors combine superior performance in high-temperature applications with a wide-range of package sizes and a choice of resistance values from 0.0002 Ω to 0.1 Ω. These state-of-the-art products deliver overload capabilities equivalent to wirewound devices and temperature coefficients as low as 75 ppm/°C. The high-power density of the WSLP enables designers to use smaller PCBs that increase manufacturing speed, reduce material costs, and weight.
