Appl. No.:

8/978657

Inventors:

Katherine M. McGuire - Downers Grove IL
Honorio Luciano - Elk Grove Village IL

Assignee:

Littlefuse, Inc. - Des Plaines IL

International Classification:

H02H 504

US Classification:

361106

Abstract:

The present invention is a device for protecting an electrical circuit. The device includes a resistive element having a first and a second surface. A first electrode is in electrical contact with the first surface of the resistive element and a second electrode is in electrical contact with the second surface of the resistive element. A first end termination electrically connects the circuit and the first electrode. A second end termination electrically connects the second electrode and the circuit. An electrically insulating layer is interposed between the first and second end terminations and is in contact with the first and second electrodes. The end terminations allow for an electrical connection to be made to both electrodes from the same side of the electrical device.

International Classification:

H01H 7120
H01H 8504
H01H 6902

US Classification:

337297

Abstract:

A thin film surface-mount fuse having two material subassemblies. The first subassembly includes a fusible link, its supporting substrate and terminal pads. The second subassembly includes a protective layer which overlies the fusible link so as to provide protection from impacts and oxidation. The protective layer is preferably made of a polymeric material. The most preferred polymeric material is a polycarbonate adhesive. In addition, the most preferred supporting substrate is an FR-4 epoxy or a polyimide.

US Classification:

337297

Abstract:

A thin film surface-mount fuse having two material subassemblies. The first subassembly includes a fusible link, its supporting substrate with a groove on side surfaces and a plurality of conductive terminal pad layers. The second subassembly includes a protective layer which overlies the fusible link so as to provide protection from impacts and oxidation. The protective layer is preferably made of a polymeric material. The most preferred polymeric material is a polyurethane gel or paste. In addition, the most preferred supporting substrate is an FR-4 epoxy or a polyimide.

Appl. No.:

8/769548

Inventors:

Katherine M. McGuire - Clarendon Hills IL

Assignee:

Littelfuse, Inc. - Des Plaines IL

International Classification:

H01C 710

US Classification:

338 22R

Abstract:

Circuit protection device having a PTC element in series with a fusible element. The device includes a PTC element having first and second electrodes in electrical contact with the PTC element. An insulating layer is disposed on the first and second electrodes. Portions of the insulating layer are removed to form first and second contact points. A first conductive layer is in electrical contact with the first electrode and wraps around the PTC element. A portion of the first conductive layer forms a fusible element. A second conductive layer is in electrical contact with the second electrode. The wrap-around configuration of the device allows for an electrical connection to be made to both electrodes from the same side of the electrical device. The wrap-around configuration also permits current to flow in series through the PTC element and the fusible element for added protection from overcurrent conditions.

Abstract:

An electrical device comprising a resistive element having a first electrode in electrical contact with the top surface of the resistive element and a second electrode in electrical contact with the bottom surface of the resistive element. An insulating layer is formed on the first and second electrodes. A portion of the insulating layer is removed from the first and second electrodes to form first and second contact points. A conductive layer is formed on the insulating layer and makes electrical contact with the first and second electrodes at the contact points. The conductive layer has portions removed to form first and second end terminations separated by electrically non-conductive gaps. The wrap-around configuration of the device allows for an electrical connection to be made to both electrodes from the same side of the electrical device.
