WSLP Power Metal Strip® Current Sense Resistors

Vishay Dale introduces WSLP power metal strip resistors, very high power (up to 3 W), low value (down to 0.0005 Ω), surface mount

Image of Vishay/Dale's WSLP Power Metal Strip Current Sense ResistorsVishay’s WSLP power metal strip current sensing resistors combine superior performance in high-temperature applications with a wide-range of package sizes and a choice of resistance values from 0.0002 Ω to 0.1 Ω. These state-of-the-art products deliver overload capabilities equivalent to wirewound devices and temperature coefficients as low as 75 ppm/°C. The high-power density of the WSLP enables designers to use smaller PCBs that increase manufacturing speed, reduce material costs, and weight.

  • Wide resistance range (0.0002 Ω to 0.1 Ω)
  • High-temperature performance (up to 170°C)
  • Tight tolerances available (to 0.5%)
  • 4 terminal/Kelvin connection available
  • Low temperature coefficients (down to ± 75 ppm/°C)
  • Low thermal EMF (< 3 µV/°C)
  • Excellent overload capability (equivalent to wirewound)
  • 3 W and automotive grade qualified
Applications
  • DC-DC converters
  • Li-Ion battery management/safety
  • Automotive engine and transmission controls, climate controls, anti-lock brakes, electric and hybrid controls for battery management
  • DC motor controls
  • Inverter controls for HVAC and white goods
  • Oil/gas down hole test/measurement equipment
