Product Description
HFCL0603/1206-series Current Sensing Resistor
The HFCL0603/1206-series are metal foil current sensing resistors designed for precise current measurement. These components utilize a MnCu alloy resistive element and are constructed with an alumina ceramic substrate, epoxy adhesion layer, and robust terminal electrodes. The protective and marking coatings are made of flame-retardant epoxy meeting UL-94-V0 requirements.
