A capacitor creates in AC circuits a resistance, the capacitive reactance. There is also certain inductance in the capacitor. In AC circuits it produces an inductive reactance that tries to neutralize the capacitive one. Finally the capacitor has resistive losses. Together these three elements produce the impedance, Z.

This article explains capacitor losses (ESR, Impedance IMP, Dissipation Factor DF/ tanδ, Quality FactorQ) as the other basic key parameter of capacitors apart of capacitance, insulation resistance and DCL leakage current. There are two types of losses:
Low loss capacitors dissipate less heat. Use of such components enables circuit designers to manage thermal issues in electronic circuits. In high RF applications, use of high ESR ceramic capacitors can lead to excessive heating. In low noise amplifiers, low ESR capacitors are used to increase efficiency and effective gain.
For medium and high voltage applications, low loss aluminum electrolytic capacitors are required. Low ESR capacitors have less power losses and internal heating problems as compared to high ESR capacitors. Apart from lowering performance, high ESR values reduce the life of an aluminum electrolytic capacitor.
In RF power amplifiers, it is easy to attain high efficiency and increased power output with low loss ceramic capacitors. Use of high ESR capacitors lowers the efficiency because a large percentage of power is wasted in form of ESR loss. Low loss capacitors dissipate less heat.
In some capacitors, such as MLCC class II, dielectric conduction losses are strongly dependent on applied voltage. Metallic terminals, electrodes, and internal wiring of capacitors exhibit resistance. This energy loss does not vary significantly with temperature and frequency.
Ceramic capacitors have very low ESR, but capacitance is reduced greatly with high bias voltage and can be expensive for large values. Ceramic capacitors are best for high frequency and large-value electrolytic capacitors are good for low frequency.
