Film Capacitors

Film capacitors are a type of capacitor that utilizes thin plastic film as their primary dielectric. The BFC247962204 capacitor is among the more commonly used film capacitors, and its application fields and working principles are discussed in this particular article.

Application Field

Film capacitors are widely used in circuit design, primarily in radio-frequency applications. Most of their uses include elimination of transient disturbances, storage of energy, coupling, and decoupling of DC applications. In addition to this, film capacitors’ low losses and low sensitivities to environmental changes make them suitable for use in a number of different sensitive circuits.

Specifically, the BFC247962204 capacitor is used for EMI/RFI suppression and noise filtering applications. Due to its low impedance over a wide frequency range, it can quickly suppress transient disturbances and RFI/EMI interferences. Its low loss characteristics also make it able to store energy in demanding applications.

In addition, due to its highly stable electrical characteristics, small size, and light weight, it is frequently used in general purpose power supplies, videos, and audios. Moreover, thanks to its excellent frequency response, the product has also found extensive applications in field-effect transistors (FETs) and Silicon-Controlled Rectifiers (SCRs).

Working Principle

Film capacitors are based on the principle that when two conducting plates are placed into a dielectric medium, electrostatic fields are produced. The electric charges move from one plate to the other through the medium and form a storage device. This is the general working principle of all capacitors. On the whole, there are two variants of capacitors – paper capacitors and film capacitors.

The BFC247962204 capacitor is based on the film capacitor’s principle. It is essentially a two-wire contactless capacitor composed of two thin metal layers that are separated by a thin plastic film. When a voltage is applied to the capacitor, electric charges are attracted to the nearest plate and remain there until the voltage is applied. The metal layers act as conductors and the plastic film acts as a dielectric, allowing the capacitor to store electrical energy, while preventing the two metal layers from coming in direct contact with each other.

The dielectric used in the BFC247962204 is a high-precision, flexible polyester film. The film is heat bonded with adhesive and metalized with aluminum, providing high-precision and reliable performance. Additionally, the capacitor utilizes advanced metallization technology and metallization films, resulting in an excellent frequency response and improved RFI shielding effectiveness.

The BFC247962204 is widely used in demanding applications due to its high stability, excellent frequency response, and low losses. As a result, it is a widely used and reliable capacitor for noise filtering and EMI/RFI suppression. Its high precision, small size, and light weight also enable it to be used in a variety of power supplies, videos, and audios.
