Specifications

The TR/3216LV-250MA fuse has a current rating of 250mA and is designed for low voltage circuits, typically up to 32V DC. The 3216 designation indicates the physical dimensions of the fuse, approximately 3.2mm x 1.6mm. It is a slow blow or time delay fuse, meaning it can withstand short-duration current surges without opening, making it suitable for circuits with inrush currents. This fuse is RoHS compliant, meaning it does not contain hazardous substances such as lead, mercury, cadmium, and hexavalent chromium. The interrupting rating of the fuse is the maximum fault current that the fuse can safely interrupt. It is crucial to select a fuse with an interrupting rating that is greater than the maximum fault current in the protected circuit.

The slow blow characteristic is particularly useful in applications where momentary current spikes are common, such as during the startup of a motor or the charging of a capacitor. This prevents nuisance tripping of the fuse while still providing protection against sustained overcurrent conditions. Its small size and surface mount design make it easy to integrate into automated assembly processes, saving time and reducing manufacturing costs.
