ABSTRACT:
Electrical devices with a PTC element including a polymer having conductive particles dispersed therein and at least one metallized ceramic electrode. The devices are made by dispersing conductive particles into a polymer to form a polymer PTC composition. The metallized ceramic electrodes include a ceramic substrate having a conductive layer deposited on its surface. The metallized ceramic electrodes are brought into contact with the PTC element, and heated while applying pressure to form a laminate. The laminate is then diced into a plurality of PTC electrical circuit protection devices.
