Bel Fuse-Circuit Protection offers a broad range of PCB Mount, Surface Mount and PTC resettable fuses. PCB Mount products include radial, standard glass and ceramic cartridge fuses. The company has been at the forefront of the industry's shift to surface mount fuse designs, such as brick and chip fuses, that incorporate the need for small, compact technology. Bel Circuit Protection also offers a complete product offering of PTC resettable fuses in both surface mount and radial styles. Fuse products are certified by many 3rd party agencies to varied performance standards. The certification marks are obtained through agencies such as UL, CSA, PSE, CCC, VDE and Semko. The fuse and PTC resettable products are all RoHS 2 compliant.
Application Note, When is a Fuse Not a Fuse - A traditional fuse consists of a piece of wire or other conductive link with a known current-carrying capacity placed in series with an electric circuit. The fuse functions solely as a safety device that is designed to melt and permanently interrupt further current flow. By operating, fuses protect circuits from damage caused by overload or short circuit current, thereby preventing overheating and even fire if a fault condition should occur.
0ZCN SMT Resettable PTC Fuses - Bel Circuit Protection 0ZCN Surface Mount PTC (positive temperature coefficient) devices feature a unique polymer formulation offering superior circuit protection, with added resettable features.
Bel Fuse-Circuit Protection Portfolio - The Bel Fuse-Circuit Protection portfolio includes one of the broadest ranges of circuit protection products on the market today. Belfuse 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 hand held devices incorporate this newer technology.
