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
