Film capacitors are passive electronic components that store energy in the form of electric charge when an external voltage is applied. The 23FD3745-F is a film capacitor that is widely used in electrical equipment for various functions such as filtering, DC blocking, and snubber circuits. This article will discuss the application fields and working principle of this particular capacitor.

Application Field

The 23FD3745-F film capacitor is widely used in industrial and consumer applications, such as audio equipment, power supplies, motor drives, and switching power supplies. In audio equipment, this capacitor is typically used for the secondary power supply, to prevent high-frequency noise. It is also used as a snubber capacitor in electronic circuits for damping and controlling oscillations. Additionally, this capacitor is used as a DC-blocking capacitor to separate an AC signal from a DC signal.

The 23FD3745-F film capacitor is suitable for applications with a voltage rating up to 250V and a frequency range from 10kHz to 1GHz. Additionally, this capacitor has an insulation resistance of 100MΩ, making it suitable for use in applications that require high insulation levels and stable performance.

Working Principle

The23FD3745-F film capacitor converts electric energy into stored electric energy when a voltage is applied across its terminals. When an external voltage is applied, the metal electrodes in the film capacitor attract electrons from the electrode closest to the negatively charged terminal, and the electrons become trapped between the metal electrodes. This phenomenon is known as the "capacitance". The capacitance of the 23FD3745-F capacitor is a measure of its ability to store electrical energy.

The working principle of the 23FD3745-F film capacitor is based on the concept of dielectric polarization. When an external voltage is applied, the dielectric material between the metal electrodes is polarized. This results in a negative charge on the side of the electrode closest to the negatively charged terminal and a positive charge on the side of the electrode closest to the positively charged terminal.

The polarized dielectric material creates an electric field across the film capacitor, which stores energy in the form of electric charge. The electric charge stored in the 23FD3745-F capacitor can then be used to drive a current or to power a circuit when the external voltage is removed.

Conclusion

The 23FD3745-F film capacitor is an effective and reliable solution for electrical applications that require a voltage rating up to 250V and a frequency range up to 1GHz. Thanks to its insulation resistance of 100MΩ, the 23FD3745-F is suitable for applications that require high insulation levels and stable performance. The working principle of the 23FD3745-F is based on the dielectric polarization of its metal electrodes, which enables it to store energy in the form of electric charge.
