Film Capacitors

BFC242043302 is a kind of film capacitors that falls in the category of metallized polyester film capacitors. It features a rectangular shaped aluminum case with insulated bottom and threaded knurled stud. The film capacitors have a narrow temperature range which makes them suitable for high pulse applications, such as high frequency communication systems and automotive audio systems.

Application Field

BFC242043302 is primarily used in mobile radio and telecom systems. The combination of its low ESR, high pulse withstanding capability, miniaturization, and high stability makes it an ideal choice for a wide range of applications, such as high pulse filtering, coupling, bypass, and snubber circuits, and base station communications system.

In addition, it\'s also used in switching power supply, electric drive control, sophisticated instruments, medical equipments, televisions, mobile phones, personal computers, and other high tech applications.

Working Principle

BFC242043302 works on the principle of dielectric field separation, where two metallic plates are separated by a dielectric film and no electrical contact is maintained between the two. The dielectric material acts as the insulating material, while the two metal plates create an electric field within the dielectric. The electric field generated by the two metal plates is kept intact due to the dielectric material. The voltage drop across the capacitor is almost zero, since there is no contact between both metal plates.

A film capacitor is basically an electronic component, which stores energy in the form of an electric field. This stored energy is then released to the external circuit. The electric field is generated between two electrodes, one of which is grounded while the other is connected to the external circuit. A dielectric material insulates the two electrodes and determines the amount of electric field stored in the capacitor.

BFC242043302 can be used to filter power supplies, filter radio-frequency signals, and reduce unwanted high frequency noise in AC circuits. They can also be used as a timing device for frequency-dependent circuits, for example, in motor speed controlling and in microprocessors. Because of their high frequency range, these capacitors are ideal for use in CE compliant products.
