The MMFR series are precision molded metal film resistors designed to address the challenges in customer design and manufacturing. Utilizing advanced precision metal film deposition technology on 96% alumina ceramic rods, these resistors achieve target resistance values through laser trimming. They offer high precision, low temperature coefficients, and excellent load life stability, making them ideal for applications requiring high accuracy and stability. The robust construction, including leaded design to reduce PCB stress, enhances their suitability for demanding environments.
