PRL Current Sense Resistors Susumu PRL Current Sense Resistors are very low resistance value chip resistors with long-side electrodes for high-precision current detection. The PRL series features excellent performance in resistance tolerance, noise, long term stability, and heat dissipation. These miniature resistors are offered in 1/3W, 2/3W, 1W, and 2W. Susumu PRL Current Sense Resistors are ideal for PC power sources, inverters, automotive electronics, adapters, and industrial machines.
