Description

The KRL7638T4 Current sensing chip resistor is part of the KRL series of 4-sided terminal metal foil low resistance chip resistors from Susumu. The KRL7638T4 model has a 3015 chip size and is available in E-6 resistance values between 0.001Ω up to 0.5Ω. This 4 terminal resistor has been designed with separated voltage terminals allowing for precise measurement of voltage. Susumu’s metal foil technology offers a power rating of 3W 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 up to 0.5Ω
  • Resistance value series of E-6
  • Tolerances of ±1%, ±2% or ±5%
  • TCR of ±50 ppm/°C or ±100 ppm/°C
  • Power rating of 3W
  • Separated voltage terminal for precise measurement of voltage
  • Temperature range of low EMF -55°C to +155°C (M)
  • Certified AEC-Q200 compliant
