Circuit Protection Portfolio

The Bel Fuse circuit protection portfolio includes one of the broadest ranges of circuit protection products on the market today. Bel Fuse has been at the forefront of the industry shift to board-level, surface-mount fuse designs, including their C2Q Chip Fuses with 0603 footprint. Many of today's smaller handheld devices incorporate this newer technology and Bel Fuse is poised to help.

The circuit protection offering also includes PCB-mount 277 V radial fuses, as well as standard glass and ceramic cartridge fuses, including axial leaded board-mounted options. Bel Fuse also offers a complete product offering in PPTC resettable fuses. And, in addition to the standard products, Bel Fuse offers a wide range of value-add options to facilitate more efficient assembly on the production line.
