ABSTRACT:
A ceramic PTCR slug has glass-bonded-aluminum layers bonded to the major opposite surfaces. Patches of silver film are bonded to selected regions of the glass-aluminum layers and stainless steel contacts are spring loaded against the silver patches. The stainless steel contacts provide good thermal isolation to the slug. The low cost contacts are complemented by the minumum use of silver in the electrode. The package provides long life under relatively heavy duty service.
