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:
What happens if a capacitor loses power?
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.
What is a low loss capacitor?
Unlike dielectric losses, metal losses are predominant at high frequencies. High ESR values can lead to excessive power loss and shortened battery life. Using low loss capacitors in coupling and bypassing applications helps to extend the battery life of portable electronic devices.
What causes electromechanical losses in a capacitor?
In most capacitors, electromechanical losses occur mainly within the dielectric material and the internal wiring. In the dielectric material, electromechanical losses are primarily caused by electrostriction. In some cases, it may be caused by piezoelectric effect. In internal wiring, Lorentz forces can cause flexing.
What are metal losses in ceramic capacitors?
In ceramic capacitors, metal losses mainly depend on the characteristics of the materials and construction. Skin effect is a common energy loss mechanism in electrodes and terminations of ceramic capacitors. This energy loss mechanism is frequency-dependent. Excessive metal losses can cause heating and thermal breakdown in ceramic capacitors.
What are dielectric losses in film capacitors?
In film capacitors, dielectric losses are the main contributor to the overall equivalent series resistance. Dielectric conduction losses refer to losses that are caused by the actual movement of charge across a dielectric material. These losses tend to be largest at high temperatures and low frequencies.
