Provided is an improved multilayered ceramic capacitor and an electronic device comprising the multilayered ceramic capacitor. The multilayer ceramic capacitor comprises first conductive plates electrically connected to first external terminations and second conductive plates electrically connected to second external terminations. The first conductive plates and second conductive plates form a capacitive couple. A ceramic portion is between the first conductive plates and said second conductive plates wherein the ceramic portion comprises paraelectric ceramic dielectric. The multilayer ceramic capacitor has a rated DC voltage and a rated AC Vwherein the rated AC Vis higher than the rated DC voltage.
