Littelfuse TR5 Antisurge Time-Delay Fuse 4A

The Littelfuse TR5 Antisurge Fuse 4A is a 4A time-delay radial leaded fuse designed to protect electronic circuits from surges and overloads.

Overview

This fuse is engineered to handle temporary inrush currents, making it suitable for safeguarding sensitive electronic equipment. Its time-delay characteristic allows it to withstand brief current spikes that commonly occur during the start-up of motors, transformers, and power supplies, helping to prevent unnecessary blowing and nuisance tripping. The TR5 antisurge design supports continuous operation of connected devices by tolerating these transient overloads.

Key Features

• Time-delay antisurge operation for brief inrush currents
• Current rating of 4A
• Voltage rating of 250V AC
• Substantial breaking capacity
• Radial leaded design for installation on printed circuit boards (PCBs)
• Compact form factor

Applications

The TR5 fuse is suited to a range of electrical and electronic applications, including power supplies and AC/DC converters, household appliances and white goods, industrial control systems and machinery, lighting ballasts and transformer circuits, and any application requiring protection from current surges.

Specifications

The fuse features a 250V AC voltage rating and a 4A rating. Its radial leaded construction supports straightforward mounting on PCBs and a secure electrical connection. Dimensions and weight are provided in the Additional Information section.

Choose the Littelfuse TR5 Antisurge Fuse 4A when your circuit requires antisurge protection that tolerates brief start-up current spikes while guarding against overloads.
