What is the term used for power loss from a capacitor due to the leakage of current through the dielectric component?

The term for power loss from a capacitor due to the leakage of current through the dielectric component is dielectric leakage. This phenomenon occurs when a small amount of electric current flows through the dielectric material that separates the capacitor plates, leading to a dissipation of energy. Dielectric leakage is particularly critical in applications where capacitors are used for energy storage or filtering, as it can affect the overall performance and efficiency of the circuit.

In contrast to dielectric leakage, capacitance loss refers more broadly to the reduction in a capacitor's ability to store charge, which can be influenced by temperature and frequency but does not specifically address current through the dielectric. Reactance loss relates to the opposition encountered by alternating current due to both inductive and capacitive components but does not specifically denote a leakage of current through the dielectric. Power leakage is a term that could apply to various contexts of energy loss but is not specifically used to describe the leakage current in capacitors. Thus, the specific terminology of dielectric leakage accurately captures the essence of the phenomenon in question.
