High precision flame-proof wire-wound resistors are a class of highly stable resistive components designed specifically for high-precision circuit systems. They are made by winding a high thermal conductivity ceramic substrate with high-precision resistance alloy wire, allowing them to provide excellent power handling and heat dissipation performance while maintaining extremely low noise and a very small temperature coefficient. Through flame-retardant resin coating encapsulation, they not only possess a lighter structure and better economy, but also offer advantages in safety and durability compared to traditional ceramic wire-wound resistors. This series of products is suitable for precision circuits requiring precise resistance control, high reliability, long lifespan, and high temperature resistance.

1. High-Precision Resistance Control

   Precision winding using highly stable resistance alloy wire ensures excellent resistance consistency and minimal temperature drift, making it particularly suitable for demanding measurement and control circuits.

2. Superior Heat Dissipation and Long-Term Stability

   A high thermal conductivity ceramic core combined with a tightly wound process allows the resistor to maintain stable operation under high power and high load conditions, preventing resistance drift due to excessive temperature rise.

3. Strong Instantaneous Overload Capacity and Extremely Low Noise

   The precision winding design can withstand instantaneous high current surges while maintaining extremely low noise characteristics, effectively reducing interference in the circuit and making it ideal for high-fidelity and high-precision electronic systems.
