Multilayer ceramic capacitors (MLCs) have become one of the most widely used components in the manufacture of surface mount assemblies, and are inherently very reliable. But because they are made of ceramics that is brittle, these normally trustworthy devices can fail unexpectedly if they are not handled right in the electronics layout design and manufacturing. MLCs can fail either immediately or (arguably much more seriously) during service. Failure mechanisms in ceramic capacitors article tells you more about how to correctly use MLCs, what not to do and how those capacitors usually fail. When you investigate failures, you should always expect the unexpected. Cracks are always bad news! The following picture of failed capacitor is from Failure mechanisms in ceramic capacitors article.
