0.22 ~ 1MΩ Metal Film Resistance Ultra Small Type Metal Oxide Film Resistors 300ppm/C
1. Electrical and mechanical stability with high reliability
2. Nonflame painting, solvent proof, and resistant to heat & humidity
3. Low annual shift due to strengthened metal oxide film
4. Low noise capable of producing high resistance values unattainable by wire wound resistors
Ultra-miniature metal oxide film resistors (flameproof) are precision resistive elements combining high reliability and miniaturized design. This product utilizes reinforced metal oxide film material and forms a dense resistive film layer through vacuum deposition technology, resulting in excellent electrical stability and stress resistance.
The resistor surface is coated with a flame-retardant protective coating, providing solvent resistance, moisture resistance, and oxidation resistance, ensuring long-term stable operation in high-temperature and humid environments.
Compared to traditional models, the ultra-miniature version features a high power density design, offering the same or higher power handling capability in a smaller size, making it ideal for space-constrained high-density circuit boards or small electronic devices.
