The Vishay Dale WSL series resistors are ideal for all types of current sensing, voltage division, and pulse applications. Produced by proprietary techniques that result in extremely low resistance values, the WSL series features all-welded construction with a solid metal Nickel-Chrome or Manganese-Copper alloy resistive element and solderable terminations. It has very low RTC (down to 20 ppm/°C and is designed to operate in a temperature range of -65 °C to +170 °C. The WSL series is available in package sizes of 0603, 0805, 1206, 2010, 2512, 2816, 2726, 3637, 3921, 5931 and 4026. Resistance values available are from 0.5Ω to 0.0002Ω, the WSL model will determine resistance value available for each package size.
