Product Description
Bourns MF-RX135/72-0 resettable fuse is designed for electrical and electronic circuit protection, with a voltage rating of 72V and a hold current of 1.35A. It features radial leads, cured flame retardant epoxy insulation, and complies with UL 94V-0 fire safety standards.
This fuse rapidly transitions from a low resistance state to a high resistance state when subjected to electrical overload or short circuits, thereby protecting sensitive components. Upon removal of the fault condition and power, the fuse resets automatically and returns to a low resistance state, enabling maintenance-free operation over thousands of cycles.
The compact dimensions (12.26mm length, 18.26mm height, and 3.1mm width) allow easy PCB integration without requiring additional fuse holders. Its radial lead design with 0.81mm diameter supports PCB mounting and soldering efficiency.
Typical applications include security systems, power supplies and transformers, power switching devices, automotive and medical equipment, instrumentation, control systems, computers, peripherals, audio-visual, and telecommunications equipment.
