Isabellenhütte CMK Series

Isabellenhütte CMK Series
The CMK surface-mount current sensing resistor series from Isabellenhütte has been developed to offer outstanding price-performance ratio. The CMK series with a resistance range of 0.01Ω to 0.1&Omega offers a temperature coefficient of below 50ppm/K (between +20°C and +60°C) over the entire ohmic range, tolerances as low as ±1% as well as good long term stability. The CMK model offers these capabilities in a 1206 chip size.
  • 2-terminal surface-mount resistor for medium power requirements
  • Resistance range available 0.01Ω to 0.1 Ω
  • Power rating 1W (at +70°C)
  • Low TCR of <50 ppm/K (between +20°C and +60°C)
  • Constant current up to 10A (0.1Ω resistor)
  • tolerance options available ±1% and ±5%
  • Applicable temperature range -60°C to +170°C
  • 1206 chip size
  • AEC-Q200 qualified

Typical applications for the CMK series include:

  • Current sensor for power hybrid applications
  • Control systems for the automotive market
  • Power modules
  • Frequency converters
  • Switch mode power supplies
  • Driver for LED light systems
