WSK Power Metal Strip® Resistors

Vishay / Dale WSK Power Metal Strip® Resistors feature a 4-terminal design, allowing for 1% tolerance down to 0.0005Ω and 0.5% tolerance down to 0.001Ω. These Vishay / Dale resistors feature 0.5nH to 5nH inductance as well as a frequency response to 50MHz. A proprietary processing technique produces extremely low resistance values (down to 0.0005Ω). The AEC-Q200-qualified WSK series features solid metal nickel-chrome or a manganese-copper alloy resistive element with low TCR. The all-welded construction of these resistors makes them ideal for all types of automotive, industrial / computing, current sensing, voltage division, and pulse applications.
