The WSLT series High Temperature, surface-mount Power Metal Strip® resistors, are available in the WSLT2010…18 (1 Watt), WSLT2512 (1 Watt), WSLT3921 (3 Watt) and WSLT5931 (5 Watt) models that are designed to operate in a temperature range of –65 °C to +275 °C. The WSLT resistors feature a tight tolerance down to ±0.5%, and low TCR values down to ±75 ppm/°C. Its robust specifications allow the WSLT series to be used for current sensing and pulse applications in harsh, high-temperature environments without sacrificing power rating or electrical performance. Manufactured using proprietary techniques that result in extremely low resistance values, the WSLT series features all welded construction with a solid metal nickel-chrome alloy resistive element. The resistor offers low inductance values and low thermal EMF of less than 3 µV/°C.


  • Provides high-temperature (+275°C) performance for use in hostile environments.
  • Enables customer to use in high temperature environments with less derating required, ie. 61% rated power at 150°C.
  • Very low resistance values: 1 mΩ to 500 mΩ.
  • Low RTC resistance element (<20 ppm/° C) results in accurate current sensing, allowing the use of lower cost ICs.
  • Operating temperature range of -65°C to +275°C.
  • Lead-free construction is RoHS Compliant.


  • Automotive – engine controls, safety controls, multi-media electronics, climate controls, anti-lock brakes
  • Industrial – oil/gas well drilling (including down-hole test/measurement equipment)
