Product Description
Bourns MF-LSMF300/24X-2 is a high power, low profile resettable fuse designed for protection of electrical and electronic circuits against excessive current. Operating at 3A hold current and 24V, this surface mount fuse automatically switches from a low resistance state to a high resistance state during overloads or short circuits, and resets when the fault condition clears and power is removed.
The fuse offers a high current rating of 20A and trip current of 5.2A with a trip time of 5 seconds, ensuring reliable protection. Its electroless nickel immersion gold plated terminals provide excellent connectivity and durability. Compact dimensions (7.98mm x 5.44mm x 1.6mm) enable space-saving design and compatibility with automated PCB assembly using Pb and Pb-free solder reflow profiles.
Operating temperature range from -40°C up to 85°C allows use in demanding environments, while a power dissipation rating of 1.5W aids thermal management. The fuse is RoHS compliant and halogen-free, supporting environmentally responsible manufacturing.
This maintenance-free resettable fuse is capable of thousands of automatic reset cycles, eliminating the need for fuse holders and replacement, providing cost and time savings. Typical applications include security systems, power supplies and transformers, automotive and medical devices, instrumentation and control, computers and peripherals, audio visual and telecommunications equipment.
