Abstract (en)

[origin: WO2015049081A1] The invention concerns a ceramic multi-layer capacitor with a base member (1) with ceramic layers (2) and first and second electrode layers (3, 4) disposed therebetween, the ceramic layers (2) comprising a ceramic material based on BaTi1_yZryO3 where 0 ≤ y ≤ 1, displaying a temperature-dependent capacitance anomaly.
