WSR SMD High Power Metal Strip® Resistors

Vishay / Dale WSR Power Metal Strip^® Resistors, are surface-mount devices that provide high power ratings up to 5W and low resistance values down to 0.001Ω. The series is ideally suited for a variety of current sensing, voltage division, and pulse applications, including switching and linear power supplies, instruments, and power amplifiers. Vishay / Dale WSR Power Metal Strip Resistors feature all-welded construction and a solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (<20ppm/°C). The series offers solderable terminations, very low inductance (0.5nH to 5nH), excellent frequency response to 50MHz, and low thermal EMF (<3µV/°C), as well as RoHS compliance.
