ELECTRICAL DEVICE

摘要

An electrical device (1) in which a resistive element (3) composed of a conductive polymer composition and two electrodes (5, 7) is made by a method in which the device is cut from a laminate (9) of the conductive polymer composition and the electrodes, is exposed to a thermal treatment at a temperature above the melting temperature of the conductive polymer composition, and is then cross-linked. The device has improved PTC anomaly over devices prepared by a conventional method in which cross-linking occurs before the cutting step.
