Capacitor Losses (ESR, IMP, DF, Q), Series or Parallel Eq. Circuit ? 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:
Excess losses can cause the dielectric to heat leading to thermal breakdown and capacitor failure. In ceramic capacitors, dielectric losses are predominant at low frequencies. At high frequencies, these losses diminish and their contribution to the overall ESR is negligible. Metal losses comprise of ohmic resistance losses and skin effect.
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.
Thinner dielectrics generally result in lower dissipation factors due to reduced energy loss. Capacitors with higher dielectric constants tend to have higher dissipation factors. This is because higher dielectric constants often correspond to higher levels of dielectric loss within the material. How do capacitor electrodes affect DF?
As we know the definition of Loss Tangent in capacitor which it is: When a sinusoidal alternating voltage is applied to an ideal capacitor, the current advances by pi/2 in phase. In the case of a practical capacitor, however, advance in phase is (pi/2 - delta), which is smaller than pi/2. “delta” is referred to as Loss Angle.
