The FKN-H series is a fusible power wirewound resistor designed for circuits requiring over current protection and controlled fusing under abnormal current conditions. Its flameproof construction uses a noncombustible insulating coating with solvent-proof and high-temperature-resistant characteristics, making it suitable for electronic circuits where fusing behavior and insulation performance are important design considerations.
The FKN-H combines wirewound resistor construction with a fusible protection function. The series features anti-surge characteristics according to IEC 61000-4-5 and is specifically suitable for half short-circuit applications in chargers. Its specified fusing time is within 60 seconds, while temperature-cycle testing covers -55°C to +200°C.

Charger Protection
The FKN-H can be applied to the over current protection section of charger circuits, particularly in half short-circuit applications identified for this series. In this configuration, the fusible wirewound resistor provides resistance during normal circuit operation and a fusing function under specified abnormal-current conditions.
Power Supply Protection Circuits
FKN-H fusible resistors can be used in power supply circuits where current limiting and controlled fusing are required. The noncombustible insulating coating and specified insulation resistance provide defined technical parameters for circuit design and component selection.
Surge-Related Protection Circuits
With anti-surge characteristics according to IEC 61000-4-5, FKN-H can be considered for electronic power and protection circuits where surge conditions are part of the design requirements. Resistance value, rated wattage and actual operating conditions should be considered during component selection.
Electronic Equipment Requiring Fusible Protection
FKN-H is suitable for electronic equipment that requires both resistor functionality and over current protection in one component. Its specified resistance range, tolerance, fusing time and temperature-cycle conditions provide practical parameters for engineering selection.
Overcurrent protected fusible wire-wound resistors are high-reliability resistors that combine current limiting, surge protection, and fuse protection.
This series is specifically designed for power supplies, chargers, and other circuit systems requiring overcurrent protection. When the current exceeds a safe threshold, the resistor automatically melts, 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.
