Semiconductor ceramics of four-cation system of transition 3d-metal oxides Cu0.1Ni0.1Mn1.2Co1.6O4 was used for the first time to development of thick film NTC thermistors. The obtained film elements possess essential thermistor effect and the values of heat constant B on the level of bulk samples of the same composition.
