Resistor Metal Element Current Sense

This specific product line is not for new designs. The metal element current sense resistor is an economical bare element. This high current resistor is rated at 1Watt, 3Watts and 5Watt and features a resistance range from 0.005 Ohms to 0.1 ohms. The element of the current sense resistors has a temperature coefficient of ±20ppm/°C and the tolerances are at ±1% and ±5%. The metal element current sense resistor design allows for maximum cooling via airflow, thus reducing the heat that goes into the PCB. Additionally, the form factor of this resistor is designed to allow for optimum current-sensing capability in compact electrical circuits.
