Abstract
A surface mount fuse having a plurality of fusible links is provided. The links are located on opposite sides of an insulative substrate or one otherwise thermally insulated or decoupled from one another. The fuse links entered to terminals that can be asymmetrically secured to the substrate to discourage improper mounting. The fuse protects multiple different circuits or loads having a same common or grounded line.

24. A method of providing circuit protection comprising the steps of:
-
placing multiple surface-mounted fuse links on a single insulative substrate; and
spacing the fuse links apart to minimize thermal coupling of the fuse links. - View Dependent Claims (25)

26. A method of providing circuit protection comprising the steps of:
-
placing differently rated surface-mounted fuse links on a single insulative substrate; and
configuring terminals communicating electrically with the fuse links differently to prevent improper mounting of the terminals. - View Dependent Claims (27)

28. A method of providing circuit protection comprising the steps of:
-
placing multiple terminals on an insulative substrate;
connecting a plurality of surface-mounted fuse links electrically to the terminals; and
metallizing at least one additional part of the substrate to (i) enhance solderability;
(ii) ease manufacturability or (iii) both. - View Dependent Claims (29)
