WSL SMD Power Metal Strip® Resistor Vishay / Dale has expanded its WSL Series SMD Power Metal Strip® Resistors to include additional values. The case size 0603 WSL series features a 0.25W to 2.0W power rating, 0.001Ω to 0.5Ω resistance range, 0.5nH to 5nH very low inductance, excellent frequency response, and low thermal EMF, as well as a solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (<,20ppm/°C). Vishay / Dale´s WSL series low-value SMD Power Metal Strip Resistor´s operating temperature range is -65°C to +170°C, and the lead free version is RoHS compliant.
