Title:
MULTILAYER CERAMIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2024/024451
Kind Code:
A1
Abstract:
The present invention provides a multilayer ceramic capacitor which has a good balance between improvement of reliability and improvement of temperature characteristics. With respect to this multilayer ceramic capacitor, a dielectric layer contains at least Ti; and if a region in the central part of the dielectric layer in the width direction and in the stacking direction, the region having a length of 800 nm in the width direction and a length of 1 nm in the stacking direction, is divided into 800 cells each having a length of 1 nm in the width direction and a length of 1 nm in the stacking direction, high-concentration cells, each of which has a molar ratio of rare earth elements of 5% by mole or more relative to 100 moles of Ti, are present at a proportion of not less than 75% but less than 100% among the 800 cells within the region.
