Abstract

The invention belongs to the technical field of electronic components, and in particular relates to a ceramic heat-sensitive element. By utilizing the resistance value change of the heat-sensitive ceramic at different temperatures, an inner electrode embedded in a conductive polymer can respond to the current change; The oblate spherical design and the 8 inner electrodes embedded in the conductive polymer are evenly distributed, so that the length difference between the inner electrodes and the outer surface is not large, and the current changes in different directions respond to further improve the sensitivity of the ceramic thermal element.

Description

technical field [0001] The invention belongs to the technical field of electronic components, and in particular relates to a ceramic heat-sensitive element. Background technique [0002] Ceramic thermal elements are widely used in household appliances and civil and industrial electrical equipment, and are often used for temperature monitoring. Due to the structural limitation of the existing ceramic thermosensitive element, the accuracy of the ceramic thermosensitive element cannot meet higher requirements. Therefore, a high-precision ceramic thermal element is required. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a ceramic thermal element to solve the problems existing in the prior art in view of the above-mentioned deficiencies of the prior art. [0004] In order to solve the above-mentioned technical problems, the technical scheme adopted by the present invention is: a ceramic thermal element, which is in...
