Film Capacitors

A film capacitor is a type of capacitor that uses a thin plastic film as its dielectric material. A film capacitor is used for various signal filtering and conditioning and for ac power supply applications. A film capacitor’s construction is the same as other types of capacitors, but uses a special film as its dielectric. The film is usually mylar or polyester and is typically characterized by its high dielectric strength and low loss. The 890334023023CS is a commonly used type of film capacitors. This article explains the application field and working principle of 890334023023CS.

Application Field of 890334023023CS

890334023023CS film capacitors are designed to provide high performance and reliability in a wide range of applications. These applications include automotive, industrial, telecommunications and power supplies. The 890334023023CS are suitable for audio signal filtering, coupling and decoupling, power line conditioning, timing, ac power supply applications, power factor correction and EMC/EMI shielding.

Working Principle of 890334023023CS

The 890334023023CS film capacitor utilizes a dielectric film as the core of its construction. The film dielectric offers several advantages over conventional dielectric materials such as ceramic and electrolytic capacitors. The major advantage is the film\'s very low resistivity, which allows it to store large volumes of energy in a small package. This makes it ideal for applications such as signal conditioning, coupling and decoupling, timing and power factor correction.

The construction of the 890334023023CS consists of two metal plates, which are both made of aluminum. The two plates are separated by a thin dielectric film, which is usually either of plastic or mylar. The film is rolled into the shape of a cylinder and sealed along the edge. The contact between the two aluminum plates and the dielectric film is established through thermally activated conductive adhesive. This adhesive provides the necessary electrical connection between the two plates and the film dielectric.

The 890334023023CS acts as a capacitor, meaning it will store an electrical charge when current is applied to it. The film dielectric enables the 890334023023CS to store large amounts of energy in a small package. The dielectric film also provides a very low loss of energy when it stores or releases electrical charge, making it highly efficient for signal conditioning and other applications.

As with all capacitors, the 890334023023CS has two electrical terminals, which are connected to the two aluminum plates. This allows for the capacitor to be connected to the circuit and for current to flow through it. The two terminals are also typically marked with a positive (+) and negative (-) sign, which indicate the polarity of the capacitor.

Conclusion

The 890334023023CS film capacitor is an essential component in many electronic applications. It is characterized by its high dielectric strength and low loss, which makes it ideal for signal conditioning, power supply applications, power line conditioning and EMC/EMI shielding. The 890334023023CS is also highly efficient and is capable of storing large volumes of energy in a small package. By leveraging the advantages of film dielectric over conventional dielectric materials, the 890334023023CS can provide high performance and reliability in a wide range of applications.
