Abstract
An NTC thermistor is formed with a planar NTC thermistor element, a pair of power-supply terminals and a case which encloses the thermistor element and the terminals inside. The planar NTC thermistor has electrodes formed on a mutually opposite pair of side surfaces and each contacted by one of the power-supply terminals. At least one of the main surfaces of the planar NTC thermistor makes a surface-to-surface contact with an inner wall of the case such that the effective thermal capacity of the thermistor element is increased. Such an NTC thermistor, when inserted in series between an electrical power source and an electrical heat source, say, of an electronic copier, can effectively suppress rush currents when the power source is switched on.
