BK/GMA-2A is a fast acting glass tube fuse designed for overcurrent protection in electronic circuits. It features a 2A current rating with a 250V AC voltage rating and a low breaking capacity design with glass tube and nickel-plated brass endcap construction. The fuse has a typical DC cold resistance of 0.066 ohms, a typical pre-arc I²t of 3.1 A²s, and a maximum voltage drop of 250mV at rated current. With a 5mm x 20mm physical size, it is designed to UL/CSA 248-14 standards and offers AC interrupting ratings of 100A at 250V and 10,000A at 125V. This fuse is suitable for general-purpose circuit protection applications requiring fast response to overcurrent conditions.
