Bourns 3.5 A Resettable Fuse 30V, Axial Leaded, Low Resistance, Automatic Reset MF-S350

The Bourns MF-S350 is a 3.5 A resettable fuse designed to protect electrical and electronic circuits against excessive current conditions. Rated for 30 V, it features an axial leaded design with quarter hard nickel terminals which ensures durability and compatibility with surface mount technology.

This fuse operates rapidly, switching from a low resistance state to a high resistance state within 3 seconds when an overload or short circuit occurs. Once the fault condition is removed and power is cycled, it automatically resets, offering maintenance free protection for thousands of cycles.

It exhibits a very low internal resistance of 0.017 ohms, resulting in minimal power dissipation (2.5 W) and efficient circuit performance. The operating temperature range from -40°C to 85°C makes it suitable for a variety of industrial and commercial environments.

Its compact dimensions of 14 mm length, 13.5 mm width, and 1.1 mm height allow integration into space-limited assemblies. The robust quarter hard nickel terminals are weldable, enhancing mechanical and electrical connection reliability.

The MF-S series fuse is widely used in security systems, power supplies, transformers, automotive devices, medical instruments, computing peripherals, audiovisual equipment, and telecommunications circuits.

The fuse features axial leaded form factor for easy circuit integration. Quick trip time of 3 seconds under overload conditions enhances protection. Very low internal resistance minimizes power loss and heat generation. Operation in a wide temperature range suits harsh industrial and commercial applications.

RoHS compliant, ensuring environmental safety and regulatory adherence. Automatic reset capability extends maintenance intervals and reduces downtime. Compact size fits into small or densely packed electronic assemblies.

Versatile applications across automotive, medical, computing, and telecommunications sectors. For reliable circuit protection solutions, explore more Resettable Fuses and related products on EnvMart.
