GFA-1/2 Description

Short technical summary and product information.

The GFA-1/2 is a board mount fuse from Eaton's GFA series, designed for subminiature circuit protection. It is rated for 500mA at 125VAC with a fast blow response time, ensuring rapid disconnection during overcurrent events. The fuse offers a breaking capacity of 50A at rated voltage, suitable for protecting sensitive electronic circuits.

 

This through-hole component features an axial lead package with dimensions of 0.146" diameter by 0.299" length (3.70mm x 7.60mm). The leads are tinned wire for solder mounting, with a lead length of 1.5 inches. The fuse is color-coded for amp rating identification.

 

Applications include protection of subminiature devices where high shock and vibration resistance is required. The fuse is UL recognized and CSA certified for reliability. It is RoHS3 compliant and has an MSL of 1 (unlimited).
