Abstract
Official abstract text for this publication.
A circuit protection device includes a fuse element placed in parallel with a PTC thermistor layer. The element and PTC thermistor layer are provided on one or more insulating substrate, such as an FR-4 or polyimide substrate. First and second conductors connect the fuse element and PTC thermistor layer electrically in parallel, such that current (i) initially under normal flows mainly through the fuse element and PTC thermistor layer at a lower drop in voltage and (ii) after an opening of the fuse element flows under normal operation through the PTC thermistor layer at a higher drop in voltage.
First claim
Opening claim text (preview).
What is claimed is: 1. A circuit protection method comprising: protecting a first electrical pathway in a device using a substrate that comprises and operates as a resettable fusing apparatus having a first electrical resistance; and protecting a second electrical pathway in the device that is electrically in parallel with the first electrical pathway with a non-resettable fusing apparatus extending along a surface of the substrate and having a second electrical resistance, wher…
