MMFR

Precision Metal Film Molded Resistor

Tight Tolerance, Low TCR, High Load Life Stability

MMFR series uses 96% alumina ceramic cores, combined with precision metal film deposition

technology, to achieve the target resistance through laser trimming. The lowest TCR of MMFR

series is ±5ppm/℃. Load life stability is significantly improved compared to general metal

film resistor. At +70℃ ambient temperature, the maximum resistance change after loading

the rated power for 1000 hours is ±0.05%, with strong moisture resistance. The pin structure

is conducive to reducing the impact of PCB stress on resistor. Highly suitable for electronic

circuits with high requirements of TCR and stability.
