Electrodes and terminations are fundamental to the construction of passive electronic components, with emphasis upon stacked ceramic solutions for capacitance, resistance, inductance and sensing in electronic circuits. Older legacy materials for electrodes and terminations include palladium and silver respectively. These electrodes and terminations are still consumed in low layer count ceramic components or in specialty chip thermistors and varistors, inductors and resistors.
