Elektron Technology has introduced the FX0442 and FX0443; two vertical, PCB-mounting fuse holder designs in Bulgin's range. Accommodating 5x20mm fuses and rated at 10A, 250V AC with maximum power dissipation of 2.5W, the fuseholders are designed and manufactured for volume applications where PCB mounting offers a fast, economic method of integrating the fuse element into the circuit. Both fuseholders have straight PC spills with either hand-release or screwdriver or tool release caps. The caps are bayonet-fitting for quick, reliable insertion and removal of the fuse. Contact resistance of both fuse holders is less than 10mΩ and insulation resistance is rated at greater than 10MΩ at 500V DC. The devices are qualified to shock-protection category PC2, meaning live parts are inaccessible with a standard test finger in accordance with IEC60529. Using nylon and polyester flame retardant materials with flammability ratings to UL94V-0 at 85˚C they pass the glow wire test to EN60695-2-12. Both also have international approvals from VDE and UL covering both the USA and Canada. The design of the fuseholders offers designers flexibility on PCB orientation with the benefits of a durable wire-free assembly.
