The SQF series thermally fusible cement resistor is a functional component integrating power resistance, thermal fusibility protection, and circuit safety protection. The product adopts a flame-retardant ceramic shell and winding structure design, providing stable resistance control under normal operating conditions. When abnormal overload or temperature rise reaches the set operating temperature, it can achieve rapid fusing protection, effectively protecting PCBs, power modules, and electronic equipment.
As a professional fusible resistor manufacturer, this series combines the dual functions of a flameproof fusible resistor and a circuit protection resistor, and is widely used in industrial control, power supply equipment, home appliances, and electronic control systems.
