Littelfuse TR5 Antisurge Fuse, 125mA, 250VAC

The Littelfuse TR5 Antisurge Fuse is a highly reliable, very fast-acting fuse designed to provide critical protection for electronic circuits against current surges and overloads. With a precise current rating of 125mA and a 250VAC voltage rating, it is engineered for applications demanding accurate and rapid interruption of fault currents.

Featuring a radial leaded style for through-hole PCB mounting, this fuse offers stable and secure connections. Its robust construction ensures a high breaking capacity of 35A AC, enabling it to safely interrupt significant overloads without sustaining damage, thereby protecting valuable downstream components.

The 'antisurge' or time-lag characteristic allows it to withstand harmless, temporary current inrushes commonly found when powering up transformers, motors, or capacitors, while still reacting very quickly to sustained overloads or short circuits. This makes it an ideal choice for a wide range of industrial and commercial electronic equipment.

With compact dimensions of 33mm in width, 43mm in height, and 15mm in depth, this fuse is suitable for use in space-conscious designs. Its radial leaded package facilitates easy installation and replacement during maintenance or prototyping. Trusted in critical protection roles, the Littelfuse TR5 series represents a commitment to quality and safety in circuit design.
