GBB-3-R is a very fast-acting ceramic tube fuse rated at 3A, designed for reliable overcurrent protection in electronic circuits. It features a 1/4" x 1-1/4" (6.35 x 31.75 mm) physical size with ceramic tube and nickel-plated brass endcap construction, and includes axial leads with 0.81 mm (0.032 in) diameter. The fuse is rated for 250 Vac and 125 Vdc operation, with AC interrupting ratings of 200A at 250 Vac and 10,000A at 125 Vac, and a DC interrupting rating of 10,000A at 125 Vdc. It exhibits a typical DC cold resistance of 0.04475 O and a typical voltage drop of 0.1816 V. This UL Recognized and CSA Component Accepted fuse is ideal for applications requiring fast response to overcurrent conditions.
