2. Features noncombustible insulating coating with solvent resistance and high temperature tolerance

3. Consistent, uniform fusing time performance

4. Exceptional anti-surge characteristics compliant with IEC 61000-4-5 standards

5. Ideal for charger half short-circuit protection applications

Overcurrent Protection Fusible Wire Wound Resistors are high-reliability resistors that combine current limiting, surge protection, and fuse protection.

This series is specifically designed for power supply equipment and chargers, and other circuit systems requiring overcurrent protection. They automatically fuse when the current exceeds a safe threshold, effectively preventing damage to the power module or motherboard.

The products comply with the IEC 61000-4-5 surge protection standard and can withstand high-energy transient impacts, making them particularly suitable for charger soft short-circuit protection and current overload control systems.

Superior Surge Resistance
Certified by IEC 61000-4-5, it can withstand transient surges up to 2KV, preventing sudden voltage surges from causing circuit component breakdown or damage.

High-Reliability Fire-Resistant Encapsulation
The outer layer uses a non-flammable insulating coating with excellent heat resistance and solvent resistance, maintaining safety and stability even under high-temperature operation or electrical faults, without combustion or explosion.

Environmentally Resistant and Long-Lifespan Design
The product has passed high-temperature, damp-heat, pulse load, and aging tests, demonstrating excellent durability and environmental adaptability, suitable for applications requiring long-term, high-load operation.

• Chargers and power adapters: Preventing soft short circuits and overcurrent damage;
• Industrial automation and control systems: Maintaining stable operation in high-load environments;
• LED drivers and lighting power supplies: Preventing sudden current surges from burning out components;
• Communication and home appliances: Providing highly reliable short-circuit and overload protection.
