Abstract

A ceramic multilayer capacitor includes a first capacitor unit, which comprises a first material, and a second capacitor units, which comprises a second material. The first and the second capacitor unit are electrically connected in parallel. At low applied voltages, the first material has a high dielectric value and, at high applied voltages the second material has a high dielectric value.
