Bourns 0.55 A Hold Current, 10 A Rating Resettable Fuse 60V, 0.9W Power Dissipation MF-SMDF050-2

Bourns MF-SMDF050-2 resettable fuse is engineered for reliable circuit protection in electrical and electronic systems, supporting a hold current of 0.55 A and capable of withstanding continuous currents up to 10 A at 60 volts. This compact fuse utilizes a very low profile surface-mount device (SMD) design with dimensions suitable for compact PCB implementations.

The fuse features fast tripping time of 3 seconds, switching rapidly from a low resistance state to a high resistance state during overloads or short circuits, then automatically resetting once the fault clears and power is removed. This maintenance-free design endows the component with an extremely long operational life, capable of thousands of reset cycles.

The terminals are electroless nickel immersion gold plated, providing excellent conductivity and corrosion resistance. Designed to operate efficiently with a power dissipation of 0.9 watts and withstand temperatures ranging from -40°C to 85°C, the fuse is RoHS compliant, reflecting its suitability for environmentally conscious manufacturing.

Its 1812 package size and reel packaging support modern automated circuit board assembly lines, improving production efficiency. The MF-SMD series is suitable for a wide array of industrial, automotive, medical, instrumentation, and telecommunications applications, including power supplies, transformers, control systems, and audio-visual equipment.
