The KRL11050T4 Current sensing chip resistor is part of the KRL series of 4-sided terminal metal foil low resistance chip resistors from Susumu. The KRL11050T4 model has a 4320 chip size and is available in E-6 resistance values between 0.001Ω 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 5W 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.
