Abstract
A ceramic composite having at least one electrical resistor run integrated into the ceramic composite, with the composite including at least one layer that covers the resistor run toward the outside. The layer covering the resistor run has at least one opening through which the resistor run can be trimmed.
Claims5
A ceramic composite, comprising:
- at least one integrated electrical resistor run forming a meandering pattern;
- and
- at least one layer covering the at least one electrical resistor run toward an outside, the at least one layer having at least one opening through which the at least one electrical resistor run may be trimmed, wherein:
- the at least one integrated electrical resistor run has at least one of junctions and seal zones at least between adjacent conductor segments in an area of the meandering pattern, a resistance of the at least one integrated electrical resistor run being adjustable by cutting at the at least one of junctions and seal zones, and
- the at least one of junctions and seal zones are situated in an area of the at least one opening and include a same resistive material as the at least one integrated electrical resistor run.
