Abstract

PURPOSE:To obtain a current limiting element which has small variation in its responsiveness due to environmental temperature and the like and a high current limiting effect by connecting a sub-conductive path in parallel with a main conductive path made of a PTC resistor, and forming the subconductive path of a PTC resistor and NTC resistors connected in series. CONSTITUTION:A sub-conductive path is connected in parallel with a main conductive path made of a PTC resistor 21, and formed of a PTC resistor 22 and NTC resistors 51, 52 connected in series. For example, V2O3 based- ceramics are used as the resistors 21, 22, and VO3-based ceramics are used as the resistors 51, 52: The resistor 21 as the main conductive path and the resistor 22 for forming the sub-conductive path are secured nearly in parallel on an AlN substrate 1 having high thermal conductivity. Further, MO electrode terminals 3a, 3b and MO electrode plates 4a, 4b are secured to both ends of the resistors 21, 22, respectively, and the resistors 51, 52 are respectively secured to the plates 3a, 4b and the plates 3b, 4b.
