Last updated:
Abstract:
A polymeric positive temperature coefficient (PPTC) tank heater features a first conductive region, a heater body, and a second conductive region, forming a sandwich. The first conductive region includes a first conductive surface connected to a first lead and a second conductive surface connected to a second lead. The heater body is a PPTC polymer matrix including a conductive filler and a semi-crystalline polymer. The sandwich includes multiple heating elements connected in series and each heating element supplies a different resistance.
