THERMISTOREN MIT NEGATIVEM TEMPERATURKOEFFIZIENTEN UND VERFAHREN ZU IHRER HERSTELLUNG

摘要

Inexpensive Mn or Mg ferrites may be used as negative temperature coefficient thermistors. Fabrication of devices with the desired high temperature coefficients is facilitated by a processing method which forms a thin layer of oxidized and high resistivity material on a low resistivity layer of ferrite material.
