Abstract:
A chip thermistor comprising:a plurality of planar thermistor elements stacked one on top of another;insulating layers each disposed between said thermistor elements and insulating one from the other of a different mutually adjacent pair of said thermistor elements; anda pair of outer electrodes;wherein each of said thermistor elements has a mutually oppositely facing pair of end surfaces, a mutually oppositely facing pair of main surfaces each extending between said pair of end surfaces, and a pair of inner electrodes;wherein each of said insulating layers entirely covers the main surfaces of the corresponding pair of said thermistor elements;wherein one of said inner electrodes is in part on one of said main surfaces and extends continuously onto one of said end surfaces and the other of said inner electrodes is in part on the other of said main surfaces and extends continuously onto the other of said end surfaces;wherein said thermistor elements are stacked through the main surfaces to together form a stacked structure with a mutually oppositely facing outer surfaces;wherein each of said outer electrodes is formed on a respective one of said outer surfaces and is electrically connected to a different one of the inner electrodes of each of said thermistor elements on an associated one of the end surfaces thereof; andwherein the inner electrodes on different ones of said thermistor elements are electrically connected to each other only through one of said outer electrodes.
