Looking for Current Sensing & Low Resistance Resistors?

The below manufacturers are all of our authorised partners that produce Current Sensing & Low Resistance Resistors or related products.

Current Sensing & Low Resistance Resistors

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 Isabellenhütte, Alpha, Riedon and Susumu. Our current sensing resistors come in various shapes and sizes including surface-mount and through-hole. With such a vast range we can cater for virtually any resistance values.
