Abstract

A resistor device for blower motor comprising one plate of PTC element having two side surfaces and a plurality of electrodes disposed on at least one of the two side surfaces. A plurality of different resistance values can be obtained from the one plate of PTC element, which makes it possible to realize a small and compact structure for the resistor device.
