WSLF2512 High Power Low Value Current Sense Resistor

Vishay Dale's WSLF2512 resistor is rated for up to 6 W and down to 0.0003 Ω

Image of Vishay Dale's WSLF2512 High Power Low Value Current Sense ResistorVishay Dale's WSLF2512 has an all metal welded construction that provides robust performance for pulse and overload conditions while also providing superior temperature stability over a wide range of ambient temperature and power conditions. The high-power capability enables designers to use the smallest resistor possible so the end product can be the smallest and lightest possible with automotive grade reliability.

  • High power density; 6 W for a 2512 size
  • Low resistance to minimize power dissipation; down to 0.0003 Ω
  • TCR down to 70 ppm/°C
  • Low inductance (< 2 nH)
  • Low thermal EMF (< 3 µV/°C)


  • Current sensing, voltage division, and pulse applications in power management for
    • Automotive electronic controls (engine, transmission, anti-lock brakes, audio, and climate controls)
    • Inverter controls for down-hole test and measurement equipment
    • Inverter controls for HVAC systems
    • VRMs for servers
