Abstract
A chip thermistor has a pair of outer electrodes opposite each other with a specified distance in between on one of the surfaces of a thermistor element and an inner electrode extending inside the thermistor element so as to overlap these outer electrodes in the direction perpendicular to the surface on which the outer electrodes are formed. An electrically insulating layer is preferably formed on the same surface as and between the pair of outer electrodes. Each of the outer electrodes may be formed with two or more layers, the outermost of the layers being of gold.
Claims8
A chip thermistor comprising:
- a thermistor element having a top surface;
- a pair of outer electrodes disposed entirely on said top surface and opposite each other with a gap of a specified width therebetween on said top surface of said thermistor element;
- and
- an inner electrode not connected to said outer electrodes and extending parallel to said top surface inside said thermistor element so as to overlap said pair of outer electrodes as seen perpendicularly to said top surface.
