Bourns 3 A 20A Current Resettable Fuse 24V, Surface Mount Technology MF-LSMF300/24X-2

Bourns MF-LSMF300/24X-2 Resettable Fuse is a high performance protective component designed for safeguarding electrical and electronic circuits against excessive current conditions. It features a 24-volt rating and supports a hold current of 3 amperes, while allowing a peak current rating of up to 20 amperes to handle transient overloads, providing reliable circuit protection.

Constructed with a low profile and surface mount technology packaging, this fuse integrates seamlessly into automated assembly processes. Its electroless nickel immersion gold plated terminals ensure excellent conductivity and resistance to corrosion, maintaining electrical integrity.

The fuse trips within 5 seconds at a current of 5.2 amps, transitioning rapidly from a low resistance state to a high resistance state, interrupting the circuit during overloads or short circuits. It automatically resets when fault conditions clear and power is removed, enabling maintenance-free operation over thousands of cycles.

With a compact size of 7.98 mm length, 5.44 mm width, and 1.6 mm height, the fuse fits efficiently onto printed circuit boards, optimizing space and enhancing design flexibility. Its temperature tolerance ranges from -40°C to 85°C, ensuring stable operation in diverse environmental conditions.

The MF-LSMF series is RoHS compliant and halogen free, compatible with both lead and lead-free solder reflow profiles, aligning with modern environmental standards. Typical applications include security systems, power supplies, transformers, automotive and medical equipment, instrumentation and control, as well as computer and telecommunications devices.

Designed for surface mount technology with low profile and high power ratings. Operates at 24 volts with a trip current of 5.2 amps and a trip time of 5 seconds. Features electroless nickel immersion gold plated terminals for reliable conductivity.

Minimum resistance of 0.02 ohms and maximum resistance of 75 milliohms ensure efficient performance. Operating temperature ranges from -40°C to 85°C for durability in harsh environments. Maintenance-free automatic reset capability allows thousands of operating cycles.
