The MMFR series of precision molded metal film resistors are designed to meet the challenges of customer design and manufacturing in precision instruments, industrial control equipment, and precision power supplies. Utilizing advanced metal film deposition technology on 95% alumina ceramic rods, these resistors achieve target resistance values through laser trimming. They offer high precision, low temperature coefficients, and excellent load life stability, making them ideal for electronic circuits with demanding requirements for temperature stability and resistance accuracy. The robust construction, including leaded terminals, helps mitigate PCB stress, and the resistors exhibit strong moisture resistance.
