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 Capacitor Voltage Power Loss (P loss) can be calculated using the following formula: C is the capacitance in farads (F). V is the effective voltage across the capacitor in volts (V). f is the frequency in hertz (Hz). DF is the dissipation factor, also known as the quality loss factor.
Figure 1 shows the tangent of loss angle of hypothetical ideal and real capacitors. In an ideal capacitor, the dissipation factor is zero, indicating no energy loss during operation. However, in an actual capacitor, various factors such as dielectric losses and electrode resistance contribute to a non-zero dissipation factor.
Capacitor Voltage Power Loss is intrinsically linked to the quality of the capacitor. High-quality capacitors typically have lower power loss. The dissipation factor (DF), which is a measure of a capacitor's inefficiency, can change with temperature and frequency, thus affecting the power loss.
Losses Impedance and ESR A capacitor creates in AC circuits a resistance, the capacitive reactance (Formula C1-3). There is also certain inductance in the capacitor. In AC circuits it produces an inductive reactance that tries to neutralize the capacitive one.
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. Capacitors exhibiting high ESR loss would consume and waste excessive battery power due to increased I2 ESR loss.
