The GDB-5A is a fast-acting glass tube fuse rated at 5A with a 250V AC voltage rating and 50A interrupting capacity. It features a 5 mm × 20 mm physical size with a glass tube construction and nickel-plated brass endcaps, designed to IEC 60127-2 standards. The fuse has a typical cold resistance of 0.014 O and a maximum voltage drop of 120 mV at rated current. Optional axial leads are available as copper-tinned wire with 0.032" diameter and 1.5" length. This fuse is ideal for general circuit protection applications in electronic equipment, industrial controls, and consumer devices requiring reliable fast-acting overcurrent protection.
