Vishay WSL 1020 Power Metal Strip Resistors

Vishay / Dale WSL1020 Power Metal Strip Resistors

Vishay / Dale WSL1020 Power Metal Strip Resistors feature a wide side terminal construction that yields a high 2 W 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 incorporate 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 foot print size ratio (2 W 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 0.003 Ω)
  • All welded construction
  • Solid metal nickel-chrome alloy resistive element with low TCR (< 20 ppm/°C over temperature range of 20 °C to 60 °C)
  • Very low inductance, 0.5 nH to 5 nH
  • Excellent frequency response to 50 MHz
  • Low thermal EMF (< 3 μV/°C)
  • Tolerance 1%
  • Dimensions 2.54 mm W x 5.08 mm L x 0.635 mm 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
