Abstract

The invention belongs to the technical field of electronic components, and particularly relates to a ceramic thermo-sensitive element. An inner electrode embedded with a conductive polymer can respondto current change by utilizing resistance value change of thermo-sensitive ceramic at different temperatures. The whole ceramic thermo-sensitive element adopts a flat spherical design, and eight inner electrodes embedded with conductive polymers are uniformly distributed, so that the length difference between each part of the inner electrodes and the outer surface is not large, the current changein different directions are responded to, and the sensitivity of the ceramic thermo-sensitive element is further improved.

Description

technical field [0001] The invention belongs to the technical field of electronic components, and in particular relates to a ceramic thermosensitive component. Background technique [0002] Ceramic thermal elements are widely used in household appliances, civil and industrial electrical equipment, and are often used for temperature monitoring. Due to structural limitations of the existing ceramic thermosensitive elements, it is difficult to meet higher requirements for the accuracy of the ceramic thermosensitive elements. Therefore, a high-precision ceramic thermal sensor is needed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a ceramic thermosensitive element to solve the problems existing in the prior art in view of the above-mentioned deficiencies in the prior art. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a ceramic therm...
