Which mechanism causes dielectric breakdown when excessive voltage is applied to a ceramic capacitor?

💡 Explanation

When excessive voltage is applied, ionic migration occurs because the electric field forces ions to move, creating conductive filaments that short-circuit the dielectric. Therefore migration leads to breakdown, rather than EMI, deformation or delamination which arise from completely different failure mechanisms.
