Ceramic capacitors

Multi-layer ceramic capacitors (MLCC) store energy in electronic devices in the form of an electrostatic field. Typically, they consist of two coated conducting plates separated by an insulating material called the dielectric. They are used in broadcasting equipment, mobile telephones, computers, electronic lighting and high voltage circuits to name but a few applications, which all have one in common: they require a high reliability.

Hence, due to their conductivity, durability, high temperature stability and oxidation resistance, palladium, and to a less extent platinum, are the materials of choice to coat multi-layer ceramic capacitors.
