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.
At high frequencies, capacitor dielectric losses are described in terms of loss tangent ( tan δ ). The higher the loss tangent, the greater the capacitor’s equivalent series resistance (ESR). In addition, the lower its Quality Factor (Q), the greater the losses (more heat dissipated) and the worse its noise characteristics.
The angle between the total impedance and its complex component is called the ‘loss angle,’ and is a figure used to summarize the ratio between the ideal and non-ideal components of a capacitor’s overall impedance. The tangent of the loss angle is usually provided, which actually simplifies things a bit.
