KOA Speer Electronics, Inc. Datasheets for Current Sensing Resistors

Current sensing resistors convert the current flowing through it to a voltage drop. Monitoring or measuring this voltage drop allows the current through the resistor to be measured. Applications for current sensing resistors include power supplies, receptacles, and battery packs.
