Product Description
Product Description
The MMFR Precision Molded Metal Film Resistor utilizes 95% alumina ceramic rods and precision metal film deposition technology, with laser trimming to achieve target resistance values. It offers a low temperature coefficient of 10ppm/ and significantly improved load stability compared to general metal film resistors. Under a +85 environment with rated power, the maximum resistance change is 0.16% over 1000 hours. Its strong moisture resistance and pin structure reduce PCB stress. Ideal for electronic circuits requiring high temperature coefficient and resistance stability.
