性サーミスタ。[Scope of Claim for Utility Model Registration] (1) In a positive temperature coefficient thermistor in which a number of through holes are opened in the element body and counter electrodes are formed on both opening surfaces,
A positive temperature coefficient thermistor, characterized in that a conductor is inserted into a part of the through hole to melt and short-circuit between the electrodes when the heat generation temperature reaches an abnormally high temperature. (2) In a positive temperature coefficient thermistor in which a large number of through holes are opened in the element body and counter electrodes are formed on both openings,
A positive temperature coefficient thermistor characterized in that an insulating coated conductor is inserted into a part of the through hole so that the insulating coat melts and causes a short circuit between the electrodes when the heat generation temperature becomes abnormally high.
