The BK/GMA-V-125-R is a fast-acting, 5mm x 20mm glass tube fuse from the GMA series, designed for overcurrent protection. It has a current rating of 125mA and a voltage rating of 250V. This fuse features an AC interrupting rating of 35A at 250V and 10,000A at 125V. Key electrical characteristics include a typical pre-arcing I²t of 0.0024 A²s and a maximum voltage drop of 2600 mV. As a RoHS compliant component with axial leads for through-hole mounting, it is ideal for applications requiring fast-acting, low breaking capacity circuit protection.
