Product Description
Bourns MF-FSMF020X-2 resettable fuse is designed for protection of electrical and electronic circuits against excessive current conditions. It features a low profile 0603 surface mount technology package measuring 1.85 mm x 1.05 mm x 0.65 mm, suitable for compact PCB layouts.
With a nominal hold current of 0.2 A and trip current of 0.5 A, this fuse rapidly transitions to a high resistance state within 0.6 seconds when overload or short circuit occurs, protecting sensitive circuit components. The fuse automatically resets when the fault condition ceases and power is removed, allowing for thousands of maintenance-free cycles.
The gold plated nickel terminal material ensures robust soldering and long-term reliability. The fuse operates reliably in a temperature range from -40°C to 85°C with a power dissipation of 0.5 watts. Minimum and maximum resistance values are 0.55 ohms and 3.5 ohms respectively.
Typical applications include USB port protection, PC motherboards and other plug and play protection, mobile phone battery and port protection, PDAs, digital cameras, security systems, power supplies, automotive equipment, instrumentation, and telecommunications.
The product is supplied on a reel for ease of handling during automated PCB assembly. It complies with RoHS environmental standards, ensuring it meets current regulatory requirements.
Compact 0603 SMT package minimizes board space. Automatic resettable operation for overcurrent protection. Fast trip time protects sensitive components quickly. Gold plated nickel terminals for reliable solder joints. Wide operating temperature range suitable for varied environments.
Low power dissipation minimizes energy loss. RoHS compliant ensuring environmentally friendly design. Ideal for USB, PC motherboard, mobile and PDA applications. Reel packaging supports efficient manufacturing processes.
This resettable fuse is ideal for industrial, commercial, and consumer electronics manufacturing requiring reliable and compact circuit protection components. Browse more Bourns Resettable Fuses and related components at EnvMart for advanced electronic circuit protection solutions.
