Specifications

The TR/3216TD4-R 4A 32V fuse has a current rating of 4A and a voltage rating of 32V. The “TD4” designation indicates a specific time-delay characteristic, allowing the fuse to withstand brief overcurrent events without interrupting the circuit. The “3216” refers to the physical dimensions of the fuse, which are 3.2mm x 1.6mm. This fuse is designed for surface mount assembly, making it compatible with automated manufacturing processes. It is constructed with materials that meet industry standards for reliability and performance. The interrupting rating of the fuse is the maximum fault current that it can safely interrupt. It is crucial to select a fuse with an interrupting rating that exceeds the potential fault current in the application circuit.

The time-delay characteristic is particularly advantageous in applications where momentary current surges are common, such as during the startup of a motor or the charging of a capacitor. By tolerating these brief overcurrent events, the TR/3216TD4-R 4A 32V fuse minimizes the risk of nuisance tripping, ensuring continuous operation of the protected equipment. Its small size and robust design make it a reliable and versatile choice for overcurrent protection in a variety of electronic applications.
