WSL SMD Power Metal Strip® Resistors

Vishay / Dale WSL SMD Power Metal Strip® Resistors feature a 0.25W to 5.0W power rating, 0.0001Ω to 0.5Ω resistance range, 0.5nH to 5nH very low inductance, and excellent frequency response. These resistors also feature low thermal EMF and a solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (<20ppm/°C). Vishay / Dale WSL SMD Power Metal Strip Resistors have an operating temperature range of -65°C to +170°C, and the lead-free versions are RoHS compliant.
