MMFR Precision Metal Film Molded Resistor
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, making it an excellent choice for electronic circuits with demanding TCR and stability requirements. The resistor utilizes 75% alumina ceramic cores with precision metal film deposition technology, achieving target resistance through laser trimming. Its leaded structure minimizes the impact of PCB stress.
