Abstract
Un dispositivo a resistori o resistore per il motore di una soffiante comprende una piastra di un elemento PTC avente due superfici laterali e una pluralità di elettrodi disposti su almeno una delle due superfici laterali. Una pluralità di valori di resistenza diversi possono essere ottenuti da una piastra di elemento PTC, il che rende possibile realizzare una struttura piccola e compatta per il dispositivo a resistori.
