Application Notes

The KRL7638 Current sensing chip resistor is part of the KRL series of long-sided terminal metal foil low resistance chip resistors from Susumu. The KRL7638 model has a 3015 chip size and is available in E-6 resistance values between 0.001Ω to 0.5Ω. Susumu’s metal foil technology offers a power rating of 4W as well as a very stable TCR, down to ±50 ppm/°C at low resistances. These resistors have been developed to withstand high operating temperatures and applications that require the use of low EMF components. The C type utilises materials that can be operated up to +175°C, whereas the M type utilises low EMF materials that are stable up to +155°C.

  • Current sensing surface-mount chip resistor
  • Long sided terminal design with a 3015 chip size
  • Resistance values from 0.001Ω to 0.5Ω
  • Resistance value series of E-6
  • Tolerances of ±1%, ±2% or ±5%
  • TCR of ±50 ppm/°C, ±100 ppm/°C or ±150 ppm/°C
  • Power rating of 4W
  • Temperature range options of high temperature -55°C to +175°C (C) or low EMF -55°C to +155°C (M)
  • Terminal types of bottom (D) or wrap-around (E)
  • Certified AEC-Q200 compliant

The Susumu KRL7638 Current sensing chip resistor is ideal for the following applications:

  • Automotive electronics
  • Power source devices
  • AC/DC converters
  • DC/DC converters
  • Motors
  • Inverters
  • Office automation equipment
