Abstract
An improved PTC fuse assembly is described. The PTC fuse assembly includes a PTC fuse having a PTC material. To expedite heating of the PTC material, the improved PTC fuse assembly includes a die package in thermal communication with the PTC material. The die package includes a die which is responsible generating heat once a threshold has been reached. To mount the die package to a printed circuit board, the die package includes leads. The leads are sufficiently flexible such that the heat generated by the die does not compromise performance of the PTC protection circuit.
