Bourns Resettable Fuse Radial Lead 4 A Hold Current, 8 A Trip Current, 30 V, 2.5 W Power Dissipation MF-R400

Bourns MF-R400 is a high-quality resettable fuse designed for protection of electrical and electronic circuits against overcurrent conditions. Rated at a hold current of 4 A and trip current of 8 A with a maximum voltage of 30 V, this component provides rapid switching from a low resistance state to a very high resistance state when subjected to electrical overload or short circuits.

Manufactured using a cured, flame retardant epoxy polymer complying with UL 94V-0 requirements, the fuse ensures enhanced safety and reliability. It features radial lead orientation and a lead diameter of 0.81 mm, making it suitable for PCB mounting and integration.

This fuse maintains stability and function across a wide operating temperature range from -40°C up to 85°C and offers power dissipation capacity of 2.5 W, optimizing thermal performance in circuit protection applications. Dimensions are compact, measuring 14.4 mm in length, 24.8 mm in height, and 3 mm in width, facilitating installation in space-constrained environments.

The MF-R400 fuse is fully compliant with UL and RoHS standards, making it a trustworthy choice for various industrial sectors including automotive, medical, instrumentation, security systems, power supplies, and telecommunications devices. Its ability to automatically reset thousands of times reduces maintenance needs and improves operational uptime.
