OverviewCapacitor markingsHistoryTheory of operationNon-ideal behaviorCapacitor typesApplicationsHazards and safety

Most capacitors have designations printed on their bodies to indicate their electrical characteristics. Larger capacitors, such as electrolytic types usually display the capacitance as value with explicit unit, for example, 220 μF. For typographical reasons, some manufacturers print MF on capacitors to indicate microfarads (μF).
