Multilayer ceramic electronic component

A multilayer ceramic electronic component, comprising:

• a stack including dielectric layers and internal electrode layers alternately stacked on one another,
• wherein the dielectric layers include 1.1×1014 to 6.1×1014 oxygen vacancies/mm3 inclusive,
• wherein the oxygen vacancies are configured to accumulate near interfaces between the dielectric layers and the internal electrode layers to generate a depolarization field opposing an electric field applied across the dielectric layers,
• wherein the depolarization field reduces an electric field in the dielectric layers to reduce heat generation in the dielectric layers, and
• wherein carrier migration associated with the oxygen vacancies increases heat dissipation in the dielectric layers such that thermal runaway is suppressed.
