High Light Flameproof fusible resistancefusible resistance 420VACResin Paint wire wound resistor
Over Temperature Protection Flameproof Resin Paint Wire Wound Fuse Resistors
Product Introduction

The over-temperature protected flame-retardant wire-wound fusible resistor is a highly reliable electronic protection component integrating current limiting, resistance, fusible protection, and a flame-retardant structure.

The product uses a flame-retardant resin coating combined with a dedicated fusible structure, which can safely melt within approximately 5 seconds in the event of circuit overload or abnormal temperature rise, effectively avoiding risks such as sparks, arcs, and explosions.

Its design conforms to multiple international standards and possesses excellent moisture resistance, surge resistance, electrical stability, and mechanical strength.

It is suitable for applications with high safety requirements, such as consumer electronics, communication equipment, power systems, and control instruments.

Product Performance and Advantages
  • Flame Retardancy and High Heat Resistance The resistor surface uses flame-retardant resin paint or high-strength silicone resin that can withstand 800℃, maintaining stability under high-temperature conditions and preventing cracking, peeling, or carbonization due to thermal stress, effectively improving the product's flame resistance and environmental adaptability.
  • Safe Fusion and High Reliability The internally integrated thermistor fuse uses a dual-layer material deposition structure, which can quickly fuse under abnormal voltage, over-temperature, or over-current conditions, ensuring no flame, no explosion, and no arc. After fusing, the resistance is greater than 2MΩ, ensuring complete circuit isolation and improving overall system safety.
  • Excellent Electrical Performance The product has passed multiple reliability tests, including temperature cycling, short-time overload, wet load life, solder heat resistance, voltage withstand, and insulation testing. It maintains good stability within a temperature range of -55℃ to 200℃, with minimal resistance change, ensuring long-term reliable electrical performance.
  • Strong Surge Resistance Compliant with IEC61000-4-5 standards, it can withstand 2kV~3kV pulse surges and a maximum DC surge current of 50A. Even under high-frequency pulse loads, the resistance change remains less than ±5%.

Typical Application Areas

Over Temperature Protection Flameproof Resin Paint Wire Wound Fuse Resistors are widely used in equipment requiring dual protection against overtemperature and overcurrent, including:

  • Consumer Electronics – such as adapters, home appliances, and small power modules
  • Computer and Communication Equipment – routers, switches, and base station circuit protection
  • Power Systems and Converters – SMPS, power controllers, and PFC circuits
  • Industrial Control Instruments – control boards, motor drive modules, and automation equipment
  • Precision Electronic Protection Devices – surge protection circuits and overload limiting circuits
  • High-Safety Electrical Systems – equipment where the risk of sparks, explosions, and thermal runaway must be avoided.
