Abstract

A ceramic heating element arrangement in which a ceramic heating element made of SiC having electrical NTC (negative temperature coefficient) properties is provided for a circuit. At least one segment is provided in the circuit, whose resistance saturates at least quasi-asymptotically at the current flow required for a desired heat development.
