Surface-mount fuse and the manufacture thereof
First Claim
1. A substrate having first and second surfaces, each surface having first, second, third, and fourth ends, the substrate also having first, second, third, and fourth sides;
- a metal strip evenly attached to the first surface of the substrate with a laminating adhesive, the laminating adhesive being disposed between the metal strip and the first surface of the substrate, the metal strip having a first connection region, a second connection region, and a fuse link therebetween having an upper surface and a side surface, the first connection region being disposed along substantially the full length of the first end of the first surface of the substrate, the second connection region being disposed along substantially the full length of the second end of the first surface of the substrate; and
first and second leads aligned substantially with and along the first and second connection regions, respectively, the first lead being conductively connected to the first connection region and horizontally projecting away from the first connection region, the second lead being conductively connected to the second connection region and horizontally projecting away from the second connection region, for connecting the fuse to the remainder of the circuit.

Abstract
A surface-mount fuse for protecting a circuit, which includes a substrate having first and second surfaces, each surface having first, second, third, and fourth ends, the substrate also having first, second, third, and fourth sides. The fuse includes a metal strip attached to the first surface of the substrate with a layer of adhesive material, the layer of adhesive material being disposed between the metal strip and the first surface of the substrate, the metal strip having a first connection region, a second connection region, and a non-linear fuse link therebetween. The fuse further includes first and second wire leads, the first wire lead being conductively connected to the first connection region and horizontally projecting away from the first connection region, the second wire lead being conductively connected to the second connection region and horizontally projecting away from the second connection region, for connecting the fuse to the remainder of the circuit. Alternatively, the wire leads can include clip leads or other terminal leads. The fuse also includes a protective layer disposed on the fuse link. A method for making the fuse is also disclosed.
