Product Description
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 ideal for electronic circuits with stringent TCR and stability requirements. The resistors utilize 75% alumina ceramic cores with precision metal film deposition technology, achieving target resistance through laser trimming. The leaded structure minimizes PCB stress impact, and the series boasts strong moisture resistance.
