Metal Film Fixed Resistor-MF

Metal film Resistor are made by depositing special treated metal film onto ceramic core in ultra high vacuum. Both ends of the core are plated with precious metal to ensure low noise and small temperature coefficient. MF Resistor are widely applied in high fidelity stereo, electronic calculators, computers, testing instruments, meters, auto controlled equipment, military devices and aerospace equipment.
