Abstract

Cet élément comporte un substrat (11) formé d'un matériau d'alumine électriquement isolante, une couche de thermistance (12) formée d'un matériau formant thermistance et disposée sur le substrat, et des électrodes (13) formées sur le substrat et connectées électriquement à la couche de thermistance, le substrat étant recouvert par un élément électriquement isolant (14) dont le coefficient de dilatation linéaire est inférieur à celui de l'alumine, de manière à recouvrir au moins ladite couche de thermistance.Application notamment aux dispositifs à thermistance.This element comprises a substrate (11) formed of an electrically insulating alumina material, a thermistor layer (12) formed of a thermistor material and disposed on the substrate, and electrodes (13) formed on the substrate and electrically connected to the thermistor layer, the substrate being covered by an electrically insulating element (14) having a linear coefficient of expansion less than that of the alumina, so as to cover at least said thermistor layer.Application in particular to the devices thermistor.
