The MMFR series is a precision metal film molded resistor designed for high-end manufacturing and precision instrumentation applications. It offers tight tolerance, low TCR, and high load life stability, utilizing 95% alumina ceramic cores and precision metal film deposition technology. Laser trimming achieves target resistance, with the lowest TCR at 10ppm/. Load life stability is significantly improved over general metal film resistors, with a maximum resistance change of 0.16% after 1000 hours at +70 ambient temperature under rated power. The leaded structure minimizes PCB stress, making it highly suitable for circuits requiring high TCR and stability. It also boasts strong moisture resistance.
