Vishay / Dale WSL1020 Power Metal Strip Resistors
Vishay / Dale WSL1020 Power Metal Strip Resistors feature a wide side terminal construction that yields a high 2W power rating in the compact 1020 case size. The WSL1020 power metal strip resistors combine its high power-to-footprint-size ratio with extremely low resistance values down to 0.003 Ω and stable resistance tolerances to 0.5%.
The advanced construction of the WSL1020 power metal strip resistors incorporates a solid metal nickel-chrome alloy resistive element with low TCR (< 20 PPM/ºC). This results in a high-power resistor with an operating temperature range of -65 °C to 170°C while maintaining the superior electrical characteristics of the power metal strip construction.
Features
