What are the causes of failure in multilayer ceramic capacitors? Basic knowledge materials are being offered.
A tendency to easily generate cracks under high electric fields! A clear explanation of the causes of failure.
MLCCs can potentially experience either catastrophic insulation breakdown or degradation insulation breakdown. Degradation breakdown tends to be easily controlled and is known to be reversible in most cases by heating above the Curie temperature for 1 to 4 hours. This temporal change is due to the ferroelectricity and volumetric response of the ceramic when cooling from the Curie temperature. This document includes not only the causes of failure for representative capacitors but also the basics of capacitors, how to choose and use them. We encourage you to read it.
