The MMFR series are precision molded metal film resistors designed to meet the challenges of customer design and manufacturing. Utilizing advanced metal film deposition technology on an alumina ceramic rod, these resistors offer high precision, low temperature coefficients, and excellent load life stability. The molded construction and pin-type terminals reduce stress on the PCB, making them ideal for high-precision instruments, industrial control equipment, and precision power supplies where temperature coefficient and resistance stability are critical.
