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/K. 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.
