Surface Mount Fuses

This low profile Omni-Blok ?Fuse Block design is available with a

choice of solder type terminals, Q.C.terminals or P .C.board mountable terminals.The PCB design is offered with either tin-plated brass termi-nals for normal applications or tin-plated beryllium copper terminals for use in caustic environments.These fuse blocks feature individual barriers which reinforce the fuse clips while providing greater protection against clip damage and electrical shock.The unique design permits self-alignment of clips to fuse cap.This, plus a one-piece clip/terminal assures low contact resistance.Multiple pole units may be broken apart to obtain desired number of poles.
