The 73M1A, 73M2A, 73M3x, and 73M5 Series Current Sensing Resistors are metal plate packaged devices designed for excellent accuracy in current detection and limiting. Featuring a robust metal plate construction with a copper alloy, these resistors offer reliable performance across a wide operating temperature range. They are suitable for various applications including current detection, current limiting, regulated battery circuits, motor control, power supplies, hard disk drives, inverters/converters, industrial equipment, and infotainment systems. The resistors are available in standard EIA package sizes with matte tin terminal finish, making them reflow capable per JEDEC J-STD-020.
