MFSA Metal Alloy Foil Current Sensing Resistors

Eaton Electronics MFSA Metal Alloy Foil Current Sensing Resistors offer low sensing resistance and high power dissipation in package sizes ranging from 0402 (1005 metric) to 1206 (3216 metric). The MFSA series is AEC-Q200 compliant and RoHS compliant. These resistors feature metal alloy film technology and are lead free and halogen free. Eaton Electronics MFSA Metal Alloy Foil Current Sensing Resistors are ideally suited for applications such as switched-mode power supplies (SMPS), voltage regulator modules, power management, and stepper motor drives.
