Vishay Intertechnology announces a new surface-mount Power Metal Strip current sense resistor that combines a high power rating up to 6 W, TCR down to ± 70 ppm/°, and extremely low resistance values down to 0.0003 Ω in the 2512 case size.

  • Power density of 192 W/in^2 allows designers to save board space in high-power circuits by
         utilizing the smallest resistor possible
  • Low TCR provides stable and accurate current measurement across a wide temperature range
  • Low resistance values minimize power losses and improve end product efficiency
  • Advanced construction incorporates a solid metal nickel-chrome, manganese-copper, or
         manganese-copper-tin alloy resistive element with low TCR (< 20 ppm/°C)
  • Proprietary processing technique produces extremely low resistance values


  • High power rating up to 6 W
  • 2512 case size
  • TCR down to ± 70 ppm/°
  • Low resistance values down to 0.0003 Ω
  • Tolerances down to ± 1.0 %
  • Low thermal EMF (< 3 μV/°C)
  • Very low inductance (< 2 nH)
  • Temperature range from -65 °C to +170 °C
  • RoHS-compliant, halogen-free, and Vishay Green


  • Current sensing, voltage division, and pulse applications
  • Power management for automotive electronic controls such as engine, transmission, anti-lock
         brakes, audio, and climate controls
  • Inverter controls for down-hole test and measurement equipment and HVAC systems
  • VRMs for servers
