Product Description
Bourns MF-USMF110-2 is a high-performance resettable fuse designed to provide fast tripping circuit protection. Operating at 6 volts with a hold current of 1.1 amperes and a maximum current rating of 40 amperes, this surface mount device comes in a 1210 package suitable for automated assembly lines.
The fuse rapidly transitions from a low resistance state to a high resistance state under electrical overload or short circuit conditions, effectively protecting sensitive electronic components. It automatically resets and returns to a low resistance state when the fault condition is removed and power is cycled. This maintenance-free functionality supports thousands of reset cycles without replacement.
Its terminals feature electroless nickel immersion gold plating, providing enhanced conductivity and corrosion resistance. The fuse operates reliably within a temperature range of -40°C to 85°C and dissipates 0.6 watts power during operation.
The resettable fuse is ideally suited for use in industrial and commercial applications such as security systems, power supplies, transformers, automotive and medical equipment, instrumentation, control systems, computers, peripherals, audio visual systems, and telecommunications equipment. The compact form factor minimizes board space requirements.
Fast tripping circuit protection for overcurrent conditions. Compact surface mount 1210 package for automated PCB assembly. Electroless nickel immersion gold plating for durable terminals. Operating temperature range from -40°C to 85°C with 0.6W power dissipation.
