Film Capacitors

BFC233862122 Application Field and Working Principle

Film capacitors, also known as plastic film capacitors, are one of the main types of capacitors that are widely used in electrical and electronic circuits. This type of capacitor is developed and manufactured from polypropylene film due to its superior electrical insulation characteristics and strong mechanical properties.The BFC233862122 is a film capacitor with a large storage capacity and a high frequency response. It has a wide variety of applications including sound reinforcement in stage and studio sound systems, AV systems, radio and television equipment and communications systems. It is also used for the purpose of storing large quantities of direct current and alternating current voltage, and as a filter capacitor in electronic circuits.The BFC233862122 consists of two silver-plated metal plates, which are covered by an insulating material layer. This layer serves to reduce electrical leakage in between the two electrical contact terminals. The capacitance value of the BFC233862122 is always determined by the size of the electrode plates, thus the larger the size, the larger the capacitance and vice versa.In addition, the dielectric constant of the film medium affects the performance and behaviour of the BFC233862122 capacitor. Accordingly, the dielectric constant of the polypropylene film is selected in accordance with the performance requirement, temperature range, and the frequency of the application.The operating principles of film capacitors are as follows. When a DC voltage is applied to the two terminals of the capacitor, usually of different polarity, the current flow will partially pass through. This flow of current will create an electric field between the two electrodes, proportional to the applied voltage—this is known as charging of the capacitors. Once the capacitor is fully-charged, a steady current of charge will be maintained on the plates of the capacitor, known as the static plate current (or leakage current).The working of the BFC233862122 can also be explained in terms of alternating current (AC) voltage applied to its terminals. The AC voltage causes the charges to oscillate between the plates of the capacitor, thus inducing an electric field which in turn constantly changes as the voltage changes. This changing electric field causes the current to flow unevenly in both directions, thus altering the size of the electric field and the amount of charge stored, thereby changing the circuit’s impedance.In conclusion, the BFC233862122 is a film capacitor developed and manufactured from polypropylene film. It has a large storage capacity and a high frequency response, and has applications in several fields, like sound reinforcement in stage and studio sound systems, AV systems, radio and television equipment and communications systems. The capacitance value of the BFC233862122 is determined by the size of the electrode plates, and its dielectric constant is selected in accordance with the performance requirement, temperature range, and the frequency of the application. Finally, the working of the BFC233862122 is explained in terms of DC and AC voltages applied to its terminals.
