PTC THERMISTOR AND VARISTOR COMPLEX ELEMENT AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A PTC thermistor and varistor complex element and a method for manufacturing the same are provided to form simultaneously a PTC thermistor element and a varistor element on a single chip. CONSTITUTION: A PTC thermistor and varistor complex element and a method for manufacturing the same comprises an accumulated PTC thermistor area, an accumulated varistor area, and a plurality of outer electrode. The accumulated PTC thermistor area is formed with a plurality of thermistor layer and a plurality of inner electrode. The accumulated varistor area is formed with a plurality of varistor layer and a plurality of inner electrode. The outer electrodes is connected the inner electrodes of the each area. The outer electrode is formed at an end portion of the complex element. In the complex element, the accumulated PTC thermistor layer and the accumulated varistor layer are manufactured by using the same material.
