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 0.001ฮฉ to 0.5ฮฉ. Susumu’s metal foil technology offers a power rating of 4W as well as a very stable TCR, down to ยฑ50 ppm/ยฐC 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 +175ยฐC, whereas the M type utilises low EMF materials that are stable up to +155ยฐC.
