Isabellenhütte SMT-PW Series

Isabellenhütte SMT-PW Series
The SMT-PW surface-mount current sensing resistor series from Isabellenhütte offers SnPb tinned connections suitable for aviation and aerospace applications being ESCC 4001/027 qualified. Designed for higher power ratings and low internal temperature rises due to the larger pad termination sizes. The Manganin® alloy resistance element has a resistance range of 0.004Ω to 4Ω, TCR of below 50ppm/K over the temperature range (between +20°C and +60°C) for resistance values of 0.010Ω or more and offers excellent long term stability. The SMT-PW model offers these capabilities in a 2817 chip size.
  • 2-terminal surface-mount resistor with large solder pads
  • SnPb tinned connections
  • Resistance range available 0.004Ω to 4Ω
  • Power rating 5W (at +105°C)
  • Constant current up to 35A (0.004Ω)
  • TCR of <50 ppm/K for values ≥0.010Ω and <100 ppm/K for values <0.010Ω (between +20°C and +60°C)
  • Applicable temperature range -55°C to +170°C
  • Tolerance options available ±0.5%, ±1%, ±2% and ±5% (depending on the resistance values required)
  • 2817 chip size
  • ESCC 4001/027 qualified
