20100066477 | FUSIBLE SUBSTRATE - A fuse element includes a substrate disposed between first and second terminals. The substrate includes an electrically insulative material. A conductive film is disposed on a first surface of the substrate and in electrical contact with the first terminal and second terminals. | 03-18-2010 |
20090261451 | CIRCUIT PROTECTION DEVICE INCLUDING RESISTOR AND FUSE ELEMENT - An integral circuit protection device includes a substrate disposed between first and second terminals. The substrate is composed of a resistive material. A first conductive layer is disposed on a first surface of the substrate and in electrical contact with the first terminal. A second conductive layer is disposed on a second surface of the substrate. A first electrically insulating layer is disposed on the second conductive layer and substantially covers the second conductive layer. The first electrically insulating layer includes an aperture. A fuse element is disposed on the first electrically insulating layer and is in electrical contact with the second conductive layer through the aperture and in electrical contact with the second terminal. The fuse element is in electrical series with the resistive material. A second electrically insulating layer is disposed over the fuse element. | 10-22-2009 |
20090251200 | MASTER FUSE MODULE - A master fuse module includes a base housing configured to be disposed on a battery, a fuse assembly connected to the base housing, and a cover disposed on the base housing. The fuse assembly includes a first generally planar portion including a first terminal, a second generally planar portion disposed generally perpendicular to the first generally planar portion, a plurality of second terminals, and a plurality of fuses. Each fuse includes a first portion in electrical communication with the first terminal and a second portion in electrical communication with one of the plurality of second terminals. A fuse element is in electrical communication between the first and second portions and provides overcurrent protection by melting when subjected to a predetermined current. A plurality of connectors connects the fuse assembly to the base housing. | 10-08-2009 |
20090102595 | FUSE WITH CAVITY FORMING ENCLOSURE - A surface mount fuse includes a substrate, a fuse element applied to the substrate, first and second terminals applied to substrate, first and second conductors connecting the fuse element electrically with the first and second terminals, and an enclosure coupled to the substrate, the enclosure covering the first and second conductors and defining a cavity overlying at least a portion of the fuse element, the cavity allowing for distortion of the fuse element upon its opening. | 04-23-2009 |
