Title:
LAMINATED CERAMIC CAPACITOR AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2013227186
Kind Code:
A
Abstract:
To achieve both a large capacity and improved reliability by maintaining flatness of a surface by forcing grains to grow as uniformly as possible by firing dielectric particles of a dielectric layer in a laminated ceramic capacitor, and by ensuring permittivity at a certain level of particle size.
In a laminated ceramic capacitor, a variation nd (a value (D90/D10) obtained by dividing the grain size D90 equivalent to a cumulative abundance of 90% by the grain size D10 equivalent to a cumulative abundance of 10%) in the average grain size of dielectric particles constituting a dielectric layer is less than four.
