Abstract
A selection method includes: obtaining or providing multilayer ceramic capacitors each having a multilayer structure in which each of a plurality of ceramic dielectric layers and each of a plurality of internal electrode layers are alternately stacked; measuring a ratio of (a current value at 10 V/μm when a direct voltage is applied to a plurality of ceramic dielectric layers at 125 degrees C.)/(a current value at 10 V/μm when a direct voltage is applied to the plurality of the ceramic dielectric layers at 85 degrees C.), with respect to each multilayer ceramic capacitor; determining whether the ratio is in a predetermined range; and selecting a multilayer ceramic capacitor or multilayer ceramic capacitors each having a ratio in the predetermined range as a desired multilayer ceramic capacitor.
