Abstract
A multilayer thermistor and a method of making it are disclosed. The thertor has a positive temperature coefficient of resistance (PTCR) and a room temperature resistance lower than prior art thermistors of the same size. The thermistor is comprised of a plurality of layers of material having the PTCR characteristic laminated in alternation with layers of electrodes, the outer two layers of the thermistor being PTCR layers. Alternate electrodes are electrically connected in common to a pair of conductors forming thereby parallel resistance paths across each layer. The more resistance paths the thermistor has, the lower the overall resistance of the device.
