Metal Glaze High Voltage Chip Resistors, Anti-Sulfuration are high-stability surface mount resistors designed for high-voltage and harsh environment applications.

This series utilizes a molded package structure that meets UL94V-0 flame retardant standards, exhibiting excellent heat resistance, moisture resistance, and anti-sulfurization properties. Even after prolonged exposure to sulfur-containing environments (such as industrial areas, automotive exhaust, and lighting power supplies), it maintains stable resistance values ​​and reliable electrical characteristics.

Excellent Anti-Sulfuration Performance
Utilizing a special anti-sulfurization alloy terminal electrode material, it effectively resists open circuits or resistance drift caused by silver sulfide formation, ensuring long-term stable operation in industrial gas or automotive environments.

Flame-retardant encapsulation design (Flameproof UL94V-0 Rated Molded Body)
The shell is made of molded plastic that meets the UL94V-0 flame-retardant standard, possessing high insulation and flame-retardant properties, effectively preventing material carbonization or combustion at high temperatures.

High Mechanical Strength and Solder Strength
The robust structure can withstand multiple reflow and wave soldering processes, suitable for high-density surface mount circuits.
