4500 Ppm/C Fusible Wire Wound Resistors Over Temperature Protection

1. Special designed themal fuse combination provides both anti-surge &over temperature protection functions.

2. Excellent anti-surge characteristics up to 2KV according to IEC 61000-4-5.

3. Suitable for the application to soft short-circuit of a charger.

4. UL 1412 approved.

Over-temperature protected fusible wire-wound resistors are high-reliability resistors that integrate overcurrent protection and over-temperature fusing functions. This series employs a dedicated thermal fusing design, which can quickly disconnect the circuit in the event of overload or abnormal temperature rise, effectively preventing damage to the power supply or charger.

The products possess excellent surge withstand capability (up to 2KV, compliant with IEC 61000-4-5 standard), maintaining stable operation even under transient high-voltage surges. They are also UL1412 certified, ensuring safety and consistency, and are particularly suitable for charger soft short-circuit protection and circuit board over-temperature protection applications.

• Dual Protection Design
• Combining over-temperature fusing and surge protection, it can quickly cut off current in case of circuit abnormalities.
• Excellent Anti-Surge Performance
• Withstanding surge voltage up to 2KV, ensuring long-term stability of power supplies and control systems.
• Highly Reliable Flame-Retardant Construction
• The casing is covered with flame-retardant ceramic, which is moisture-resistant and heat-resistant, ensuring electrical safety.
• International Certification Guarantee (UL1412 Approved)
• The product complies with international safety standards and is suitable for use in electronic products worldwide
