Film Capacitors

A Film Capacitor, or plastic capacitor, is a type of capacitor featuring a thin plastic film as an insulating dielectric material. Film types include polyester, polystyrene, polycarbonate, polypropylene, and polyphenylene sulfide. Film capacitors provide stability of characteristics with age and temperature, and have a high degree of self-healing.

BFC236865683 Application Field and Working Principle

The BFC236865683 is a 3-pole film capacitor from Murata, with a Rated Voltage of 2,000 VDC and a Rated Current of 100 μA, and featuring lower leakage current and a compact size. It is suited for a variety of applications, such as electric vehicles, energy storage, and high-voltage inverters. It is also used in various power electronics, industrial, and consumer applications.

The primary function of a film capacitor is the same as that of a conventional capacitor, to filter or store electricity. When a voltage is applied to its terminals, an electric field is established across its plates and dielectric layer, causing charge to accumulate. This creates a large energy storage device for temporary use in pulsed power supplies. The film capacitor also helps to reduce interference that couples from other circuitry, as the film provides excellent isolation between the terminal plates. It also helps to reduce harmonics in power supplies and reduce voltage spikes.

The working principle of the BFC236865683 is based on the idea of electrical static charge storage in a dielectric material. This is done by producing a static electric field between the capacitor\'s two metal plates (electrodes) and the dielectric material. The simple equation used to calculate the total capacitor charge in Farads is:

where:

• C is the total capacitor charge stored (Farads)
• ε is the permittivity of the dielectric material (Farads per meter)
• A is the area of the capacitor plates (square meters)
• d is the distance between the plates (meters)

In the BFC236865683, the dielectric material is an ultra-thin plastic film, which is used to provide excellent insulation between the two capacitor plates. When a voltage is applied to the capacitor, it will start to charge and then store the charge. This allows the capacitor to act as a buffer, temporarily storing energy and releasing it when needed.

The BFC236865683 is also highly suitable for use in applications where high-frequency noise needs to be filtered out. This is due to the fact that the capacitor is able to reduce the noise at high frequencies due to its high-frequency characteristics. This type of capacitor is also commonly used in oscillators, power supplies, and other high-frequency circuits.

In summary, the BFC236865683 film capacitor is a highly reliable and powerful capacitor, suitable for a variety of applications, such as electric vehicles, energy storage, high-voltage inverters, and more. It offers excellent insulation between the plates and helps to reduce interference, harmonics, and voltage spikes in power supplies. The working principle of the capacitor is based on the static electric field generated between the capacitor\'s two metal plates and the dielectric material. It is able to store and release energy when needed.
