Metal Oxide Film Resistors, Flameproof
- Electrical and mechanical stability with high reliability
- Nonflame painting, solvent proof, and resistant to heat & humidity
- Low annual shift due to strengthened metal oxide film
- Low noise capable of producing high resistance values unattainable by wire wound resistors

Product Overview
These fire-resistant metal oxide film resistors are manufactured using high-performance metal oxide films, exhibiting excellent electrical and mechanical stability to ensure long-term reliable operation. Their surface is coated with a fire-resistant coating, effectively resisting high temperatures, humidity, and chemical solvents, making them suitable for electronic applications in various harsh environments.
Furthermore, this series of resistors, through an improved film structure, significantly reduces annual resistance variation and noise output, providing superior resistance performance and making them an ideal replacement for traditional wire-wound resistors.
