Current Sensing / Low Resistance

Current Sensing / Low Resistance

Current sensing resistors are resistors used for measuring current in the circuit which can be converted using Ohm’s Law into a voltage reading. They usually come in very low resistance values, often measured in micro Ohms. At Rhopoint Components we offer a wide range of current sensing resistors by leading manufacturers including Isabellenhutte, Alpha, Caddock, Riedon and Susumu. Our current sensing resistors come in various shapes and sizes, surface-mount and through-hole, and we can cater for virtually any resistance value.
