PTC THERMISTOR CHIP AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention addresses to provide a chip PTC thermistor that can easily be inspected the soldered portions after it is mounted on a printed circuit board and that can be used in a flow soldering process. A chip PTC thermistor of the present invention includes: a first main electrode(12a) and a first sub electrode(12b) on a first surface of a cuboidal form conductive polymer having the PTC characteristics, a second main electrode(12c) and a second sub electrode(12d) on a second surface opposing to the first surface of the conductive polymer. Between the first sub electrode(12b) and the second sub electrode(12d), and between the first sub electrode(12b) and the second main electrode(12c) are electrically connected with a first side electrode and a second electrode(13a, 13b) respectively.
