In this work, single-phase La_{0.7}Sr_{0.3}Zr_{0.5}Co^{2+}_{0.2}Co^{3+}_{0.3}O_3 and La_{0.8}Sr_{0.2}Ti_{0.5}Co^{2+}_{0.3}Co^{3+}_{0.2}O_3 ceramics with the stable perovskite structure were utilized for fabrication of multilayer negative temperature coefficient thermistors. The number and thicknesses of ceramic layers were adjusted to attain suitable resistances in a desired temperature range. Scanning electron microscopy studies revealed a dense, fine-grained microstructure of ceramic layers, lack of delaminations and cracks at ceramic layer-conductive layer boundaries and a good cooperation with conductive layers. The temperature coefficients of resistance of the fabricated multilayer thermistors were changing from - 13 to - 1%/K in the temperature range from - 55 to 400C.
