Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates.
In ceramic capacitors surges with low energy and high voltage can increase current leakage.
Failure of ceramic capacitors due to pcb flexure is a common problem.
A high energy surge may crack the ceramic and let in moisture providing a conductive path.
Failure mechanisms in ceramic capacitors design and process issues handling damage causes of flexure damage 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.
