Film Capacitors

Film capacitors, also known as film dielectric capacitors, are components used to store electrical energy. They consist of a thin dielectric film encapsulated in metal and plastic enclosures, which are then connected to electrode pins. The dielectric film can be polyester, polypropylene, polystyrene, teflon, acrylic, BOPP and other similar materials. They have been widely used in AC and DC applications such as commercial, consumer, industrial and medical electronics. In addition to their excellent electrical characteristics, film capacitors also have good environmental stability, robustness and reliability.

F1778347K3FLB0 Application Fields and Working Principle

The F1778347K3FLB0 capacitor is a plastic, epoxy encapsulated film capacitor with a capacity of up to 7uF. It is constructed with a 10KV – rated dielectric film, which makes it suitable for a wide range of voltage. This capacitor offers high reliability, low ESR and low acceleration in time and voltage. The F1778347K3FLB0 is mainly used in DC circuits to store charge and AC circuits to filter out high frequency signals. It is commonly used in industrial, digital and consumer electronics. Additionally, it can be used in applications that require high voltage, such as power amplifiers.

The F1778347K3FLB0 capacitor works by utilizing the physical property of a dielectric material. When a dielectric material is placed between two metal plates, a capacitance (C) is formed and an electrical charge (Q) can be stored in the capacitor. The capacitance of the capacitor is determined by the area of the plates (A), the distance between the plates (t) and the dielectric’s relative dielectric constant (K).

The charging and discharging of the capacitor is caused by an electric current. The current flows between the two metal plates and is charged or discharged according to the current’s amplitude and frequency. When the capacitor is charged, the electric field generated by the electric current increases the electric potential between the two plates. Similarly, when the capacitor is discharged, the electric field decreases the electric potential between the two plates.

The F1778347K3FLB0 capacitor provides excellent electrical characteristics, including low ESR, high ripple handling capacity and high temperature stability. The operation of the capacitor is fairly robust over an extended temperature range and it is able to withstand very high electrical pulses. In addition, the capacitor has a low rating for ESR and has excellent surge and surge overload characteristics.

The F1778347K3FLB0 capacitor is well suited for AC and DC applications that require long life, high reliability and high surge capabilities. It is most often used in high voltage applications, such as power amplifiers, industrial switching and consumer electronics. It is also relevant for consumer electronic applications, such as audio equipment, motion control systems and automotive electronics.
