Surface-mount resistors in power ratings up to 7 W

TE Connectivity

TE Connectivity (TE) supplies the SM series of surface-mount power resistors which offer mechanical strength and reliability, feature a low-profile case design with flexible tinned copper terminations for reliable solder joints.

The SM series resistors are available in versions with power/voltage ratings of 2 W/300 V, 3 W/500 V, 5 W/500 V, or 7 W/750 V. Tolerance of resistance is either ±1% or ±5%.


All parts in the series use a fully welded construction technique, unlike other designs that rely solely on tinned termination connections. This construction enables the SM series resistors to withstand the higher temperatures associated with reflow, vapor phase or infrared manufacturing processes without degradation.


  • Resistance-value range: 10 Ω to 2 MΩ
  • Temperature coefficient of resistance:
    • Metal film versions: ±100ppm/°C
    • Wire versions: ±200ppm/°C
  • UL94V0 flameproof coating
  • Operating-temperature range: -55°C to 200°C


  • Industrial equipment
  • Consumer devices
