Isabellenhütte SMP-PW Series

Isabellenhütte SMP-PW Series
The SMP-PW surface-mount current sensing resistor series from Isabellenhütte offers SnPb tinned connections suitable for aviation and aerospace applications being ESCC 4001/027 qualified. The design for high power ratings and low internal temperature rises due to the larger pad termination sizes. The Manganin® alloy resistance element has a resistance range of 0.005Ω to 1Ω, TC of below 50ppm/K over the temperature range of +20°C to +60°C and offers excellent long term stability. The SMP-PW model offers these capabilities in a 2010 chip size.
  • 2-terminal surface-mount resistor with large solder pads
  • 0.005Ω to 1Ω resistance range available
  • Power rating 3W (at +70°C)
  • Constant current up to 24A (0.005Ω)
  • TCR of <50 ppm&/K (between +20°C and +60°C)
  • Applicable temperature range -65°C to +170°C
  • Tolerance options available ±0.5% and ±1% (depending on the resistance values required)
  • 2010 chip size
  • ESCC 4001/027 qualified

Typical applications for the SMT series include:

  • Aviation and aerospace applications
  • Control systems for the automotive market
  • Current sensor for power hybrid applications
  • Frequency converters and power modules
  • Switch mode power supplies
