Abstract

Resettable fuses have been widely used in overcurrent or overtemperature circuit protection designs in computers, automotive circuits, telecommunications equipment, and medical devices. Abnormal behavior of a resettable fuse can damage a circuit. This paper identifies and experimentally assesses the failure precursor parameters of a polymer positive temperature coefficient resettable fuse. It is shown that the degradation of the resettable fuse can be monitored, detected, and predicted based on the monitoring of these precursor parameters.
