ABSTRACT:
A self-regulating positive temperature coefficient (PTC) heater assembly and a method of manufacturing the heater assembly are disclosed. The PTC heater assembly includes at least one PTC heating element and a pair of spaced electrodes. Each electrode includes a first side, the first sides of the pair of electrodes being spaced from one another, wherein the at least one PTC element is located between, supported by and energized by the pair of electrodes. The at least one PTC element is oriented approximately transverse to a longitudinal axis of the pair of spaced electrodes. An electrically insulative and thermally conductive interface pad is interposed between and contiguous to the first side of at least one of the pair of electrodes and a wall of the PTC element. A pair of power leads, one being connected to each of the pair of electrodes, energizes the pair of electrodes.
