FCN2825E224K-Y

Film capacitors are divided into two general categories: metallized film capacitors and non-metallized film capacitors. FCN2825E224K-Y belongs to non-metallized film capacitors. Its construction is divided into a film, a dielectric, and leads. The metallized film is composed of a carbon film or a polyester film as the support and an Al-film or Zn-film as the metallized film, and the metallized film is an aluminum-zinc alloy film, whose composition can be up to three parts aluminum and one part zinc.

FCN2825E224K-Y is a non-metallized film capacitor and is specifically a polyethylene naphthalate (PEN) film capacitor. In addition to PEN, the materials used to construct this capacitor\'s dielectric include polystyrene (PS), polycarbonate (PC) and polypropylene (PP). PEN film capacitors possess excellent volumetric efficiency, low ESR, and extremely low warping characteristics compared with other polymeric film capacitors, such as polypropylene.

The working principle of FCN2825E224K-Y is similar to that of most other capacitors. It stores energy in the form of an electric field between two conducting surfaces, which are separated by an insulator known as a dielectric. When DC voltage is applied to the capacitor, electric charges accumulate at these two electrodes. The electric field between the electrodes accumulates the energy for the capacitor. When alternating current (AC) voltage is applied, the electric field will go up and down with the AC voltage, which allows the capacitor to store energy by switching rapidly between storing and releasing energy.

FCN2825E224K-Y capacitors have many applications. They are widely used in high-frequency communication systems, loudspeakers, power supplies, and electronic equipment. They can also be used in filter networks, impedance matching networks, and AC or DC discharge circuits. In addition, they are often used in consumer and professional audio systems, signal processing circuits, electronic control systems, TV/Video devices and automobiles.

In conclusion, FCN2825E224K-Y is a non-metallized film capacitor which utilizes a polyethylene naphthalate film with an Al-film or Zn-film for its metallized film. It is known for its excellent volumetric efficiency, low ESR, and extremely low warping characteristics. Its applications include high-frequency communication systems, loudspeakers, power supplies, and electronic equipment, as well as filter networks, impedance matching networks, and AC or DC discharge circuits.
