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:
The effective gain and efficiency of small signal level amplifiers can be increased by the use of low loss capacitors. As an example, the thermal noise (KTB) of a low noise amplifier (LNA) can be minimized by employing low loss ceramic capacitors in the design.
Another key parameter is the ripple current rating, Ir, defined as the RMS AC component of the capacitor current. where Pd is the maximum power dissipation, h the heat transfer coefficient, A is the area, T is the temperature difference between capacitor and ambient, and ESR is the equivalent series resistor of the capacitor.
Some examples of the advantages are listed below for several application types. Extended battery life is possible when using low loss capacitors in applications such as source bypassing and drain coupling in the final power amplifier stage of a handheld portable transmitter device.
Dielectric loss tangent of ceramic capacitors is dependant upon specific characteristics of the dielectric formulation, level of impurities, as well as microstructural factors such as grain size, morphology, and porosity (density). Each dielectric material has an associated loss factor or loss tangent.
