ABSTRACT:
A PTC-resistor includes a base body made of a ceramic material with a positive temperature coefficient of resistance. The base body extends along a median plane, and is confined by surfaces. At least one surface is configured to electrically connect the base body. An area of the at least one surface is larger than an area of a parallel projection of the base body in a direction perpendicular to the median plane.
