New PCB mounting Bulgin Fuseholders

Elektron Technology, owner of the Arcolectric, Bulgin and Sifam electronics manufacturing brands, introduces the FX0442 and FX0443; two new vertical, PCB-mounting fuseholder designs in Bulgin’s already extensive fuseholder range.

Accommodating 5 x 20mm fuses and rated at 10A, 250Vac with maximum power dissipation of 2.5W, the FX0442 and FX0443 are designed and manufactured for volume applications where PCB mounting offers a fast, economic method of integrating the fuse element into the circuit.

Both the FX0442 and FX0443 have straight PC spills with either hand-release or screwdriver/tool release caps. The caps are bayonet-fitting for quick, reliable insertion and removal of the fuse. Contact resistance of both fuseholders is <10mΩ and insulation resistance is rated at >10MΩ at 500V d.c.

Both fuseholders 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 fuseholders also have international approvals from VDE and UL covering both the USA and Canada.

“Elektron Technology is proud to introduce quality products like the FX0442 and FX0443 that offer engineers tangible benefits through what are actually quite simple design enhancements”, points out Owen Kivlin, Technical Director of Elektron Technology. “The design of the FX0442 and FX0443 offers designers another degree of flexibility on PCB orientation with the benefits of a durable wire-free assembly. PCB mounting certainly improves the build quality of the end products, as well as being easier to assemble”.
