Vishay / Dale WSL1020 Power Metal Strip电阻器

Vishay / Dale WSL1020 Power Metal Strip电阻器 在1020小外形尺寸内采用宽边接头结构,实现2W高功率等级。WSL1020 Power Metal Strip电阻器将高功率尺寸比与低至0.003Ω的电阻值及0.5 %的稳定电阻公差结合在一起。WSL1020 Power Metal Strip电阻器的先进结构将固体金属镍铬合金电阻芯与低TCR(< 20 PPM/℃)相结合。使这一高功率电阻器实现 – 65 ℃到+ 170 ℃的工作温度,同时又保持着Power Metal Strip结构优异的电气特性。

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.
