Film Capacitors

Film capacitors are amongst the most important types of electronic components. They are used in a range of electronic circuits, including for filtering and for transducer applications in sound systems. They can also be used to couple signals, provide power supplies and for various other uses.

The B32921C3473M000 is one such type of film capacitor. It is a metallized polypropylene film capacitor with a pitch of 7.5mm, a dielectric thickness of 0.06mm, an insulation resistance of greater than 10000MΩ and a capacitance of 470nF. It is designed for operation in alternating current and direct current circuits with a rated voltage of 250VAC, a peak voltage of 400VAC and a rust-proof wedge terminal connection.

Application Fields of B32921C3473M000

The B32921C3473M000 is a versatile film capacitor, offering a range of applications due to its features and design. It is chiefly employed in interference suppression, power supply filtering and in DC coupling applications. It can also be used for filtering in transducer and sound systems, for voltage compensation and for buffering signals.

Due to its superior dielectric resistance and insulation, the B32921C3473M000 is particularly well-suited to be used in conditions with high humidity levels and where there is potential for a large amount of vibration in the environment.

Working Principle of B32921C3473M000

The B32921C3473M000 is a metallized polypropylene film capacitor, which acts by taking a current or voltage and storing it in the form of an electrical field. This is done by filling between two electrodes known as plates, contained within the capacitor. The capacitor acts as a kind of electricity store. When a voltage is applied to it, it accumulates this charge until the voltage is removed. The capacitance of the capacitor is defined by the amount of charge it can store and is normally measured in farads.

The stored charge in a capacitor can later be used for various purposes. For example, in a low-pass filter circuit, it can be used to reduce the size of the signal, allowing high-frequency signals to pass and low-frequency signals to be blocked. It can also be used to boost the signal, allowing weaker signals to be amplified. In DC coupling applications, it is used to prevent excess current from flowing through the circuit, providing an additional resistance or impedance.

Since capacitors require an alternating voltage to store a charge, the B32921C3473M000 comes with surge-proof wedges that help to dissipate any potential surges which may occur in the system. This feature also helps to keep the internal dielectric resistance at an acceptable level, ensuring that the capacitor is operating effectively within its specified voltage rating.

Conclusion

Film capacitors are extremely versatile and can be used in a variety of applications. The B32921C3473M000 is one such example, offering a range of features such as a metallized polypropylene film, rust-proof wedge terminals and a high insulation resistance. It is suited for use in interference suppression, power supply filtering, transducer and sound systems, voltage compensation and signal buffering. Its working principle relies on storing an electrical charge in the form of an electrical field. This makes it useful for various uses, such as in low-pass filter circuits, DC coupling and for signal amplification.
