Product Description

 

Nonflammable Cylindrical Fixed Metal Oxide Film Resistor MOF 0.25W 0.5W 1W 2W 3W 5W

 

The difference between metal oxide film resistors and carbon film resistors

 

One is reducing, the other is oxidizing.The surface color of oxide film resistors is mostly gray, with rough surface, rarely blue or beige. Carbon film resistors are mostly blue in appearance. Beige, seldom gray.Metal oxide film resistance, low temperature coefficient, low current noise, moisture resistance, anti-oxidation, strong overload capacity, long-term stable work, wide operating temperature range, and metal oxide film resistance can be formed as required.These Metal Oxide Resistors offer excellent performance in applications where stability and uniformity of
characteristics are desired. They provide lower cost alternatives to Carbon Composition Resistors and General Purpose Metal Films. Metal Oxide also can replace many low power General Purpose Wire wound applications, saving both money and time, with shorter delivery cycles.
