1. Super heat dissipation with small linear temperature coefficient
2. Instant overload capability with low noise figure and low annual shift on resistance values
3. Flameproof construction with lightweight design and lower cost than enamel types
4. Durable winding wires that outperform enamel types in high temperature environments
Fire-resistant miniature wire-wound resistors are precision resistive elements that combine high power handling capacity with excellent heat resistance.
This series utilizes a high thermal conductivity ceramic substrate and premium resistance alloy wire, exhibiting superior heat dissipation efficiency and an extremely low linear temperature coefficient, ensuring stable operation under high temperature and high load conditions.
The surface is coated with a fire-resistant coating, effectively preventing combustion and arcing, providing enhanced safety compared to traditional enameled resistors.
The compact design allows for high power density while maintaining a compact size, offering greater installation flexibility, particularly suitable for space-constrained power modules and compact electronic control systems.
Its lightweight package not only saves installation space but also reduces assembly costs, providing a more reliable solution for modern high-density electronic designs.
