Abstract
An electrical component which has a base body that comprises a ceramic material and at least two contact regions arranged on the base body to which terminal elements are secured, is enveloped by a protective layer containing organic constituents, and has an intermediate layer that is arranged between the base body and the protective layer and is composed of an intermediate layer material that is both hydrophobic as well as lipophobic. The intermediate layer can be advantageously composed of a fluoropolymer which is manufactured by immersing the base body into a fluid that dissolves this polymer. The moisture stability of the electrical component is critically improved by the intermediate layer. The components are particularly employed as hot-carrier thermistor temperature sensors.
