Wire Wound Resistors, Flameproof ( Small Type )
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
Product Overview
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.
