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 alumina ceramic cores and precision metal film deposition technology. The leaded structure minimizes PCB stress, making it ideal for circuits demanding high TCR and stability.
