Before we talk about the power factor of CBB21 - film capacitors, let's first understand what power factor is. In an AC circuit, power factor (PF) is defined as the ratio of real power (P), which is the power that actually does useful work, to apparent power (S). Apparent power is the product of the voltage (V) and current (I) in the circuit. Matematicky sa to dá vyjadriť takto:
,, a. Although the power factor of these capacitors generally falls within the 0.001 - 0.002 range at standard test conditions, there may be slight variations due to differences in capacitance values, voltage ratings, and manufacturing processes.
