The KRL2550 Current sensing chip resistor is part of the KRL series of short-sided terminal metal foil low resistance chip resistors from Susumu. The KRL2550 model has a 2010 chip size and is available in E-6 or E-12 resistance values between 0.005Ω to 0.5Ω. Susumu’s metal foil technology offers a power rating of 1.5W 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.
