5.1Ohm 2WS Composite Fuse 1A Thermal Fuse Resistor IEC 61000-4-5

A composite fuse resistor is a high-performance resistive device that integrates resistance function and overload protection mechanism. It uses a composite material encapsulation and can automatically melt and break when the current exceeds the rated value, thus protecting the circuit from overload damage. This resistor not only effectively absorbs overcurrent but also cuts off the circuit in abnormal conditions, preventing electrical equipment from being damaged due to overload. It is widely used in household appliances, power systems, instruments, and other equipment, providing long-term and reliable protection for electronic systems.

1. High Heat Resistance and Overload Protection
   The composite fuse resistor uses high-temperature heat-resistant materials, enabling stable operation in high-temperature environments and effectively withstanding instantaneous overloads, protecting the circuit from damage.
2. Precise Current Protection
   This resistor can quickly cut off the circuit when the current exceeds the rated value, preventing electrical system failure due to overload and ensuring safe equipment operation.
3. Low Temperature Drift and Stability
   The composite resistor has a low temperature coefficient, maintaining a stable resistance value under different environmental conditions, ensuring high reliability during long-term use.
4. Enhanced Safety Design
   Utilizing a non-flammable coating and high-temperature resistant materials, it effectively prevents fires or other safety hazards caused by overheating or short circuits.
