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

  • Wide side terminal construction that yields high power to footprint size ratio (2W in 1020 package)
  • Ideal for all types of current sensing and pulse applications including switching and linear power supplies, instruments, power amplifiers, and shunts
  • Proprietary processing technique produces low resistance values (down to 0.003Ω)
  • All welded construction
  • Solid metal nickel-chrome alloy resistive element with low TCR (<20 ppm/°C over a temperature range of 20°C to 60°C)
  • Very low inductance, 0.5nH to 5nH
  • Excellent frequency response to 50MHz
  • Low thermal EMF (< 3 μV/°C)
  • Tolerance 1%
  • Dimensions 2.54mm W x 5.08mm L x 0.635mm H

Applications

  • Current sensing and pulse applications, including switching and linear power supplies, instruments, power amplifiers, and shunts
  • Automotive electronic controls such as engine, brushless DC motors, anti-lock brakes, climate, and battery management controls
  • Industrial controls, including down-hole test/measurement equipment for oil/gas well drilling
  • Inverter controls for HVAC systems
  • DC/DC converters for servers, VRMs for laptops, and Li-Ion battery safety and management
