Film Capacitors

Film capacitors are electrical components that employ a thin layer of dielectric material as the primary medium of insulation. In many cases, they are known as plastic, or plastic film capacitors. These devices, which are available from a variety of manufacturers, are ideal for applications that require both insulation and high frequency performance.

The R82DC3470DQ60K film capacitor, for example, is an insulation-grade, multilayer dielectric film capacitor manufactured for use in electrical and electronic applications. It is constructed from stacked layers of metallized film and dielectric film. The metallizations of the capacitor layers are formed from copper and aluminum. The dielectric film layer consists of polyethylene naphthalate (PEN) and polyethylene terephthalate (PET).

The R82DC3470DQ60K capacitor is designed to offer robust performance in general-purpose and high-frequency applications. It is designed to be highly stable, even when exposed to extremes in humidity or temperature. The device also provides excellent dielectric absorption, leakage, and voltage breakdown characteristics. Furthermore, its ESR value is low, ensuring reliable signal transmission.

The R82DC3470DQ60K capacitor has a capacitance range of 1.0 to 3.2 μF, with a tolerance of ±20%. The maximum dissipation factor is 0.08, and the maximum capacitance is 0.15 µF. It has a rated voltage of 63 V, and a maximum working voltage of 70 V. The operating temperature range is -40°C to +85°C.

The working principle of a film capacitor is relatively straightforward. When a voltage is applied to the capacitor, the dielectric film, which is between the two plates, accumulates charge and stores energy. This stored energy is proportional to the voltage applied and results in a measurable capacitance. When the applied voltage is removed, the charge dissipates and the energy stored in the capacitor is released.

Film capacitors can be used in a variety of applications, including power supply circuits, RF electronics, audio systems, and automotive electronics. The R82DC3470DQ60K is particularly well-suited for high-frequency switching applications, thanks to its low ESR and excellent dielectric absorption properties. It can also be used as a coupling capacitor in power supply circuits, and is a suitable choice for general-purpose circuit installations.

In summary, the R82DC3470DQ60K is a multilayer plastic film capacitor ideal for high frequency applications, including those requiring high insulation and stability. It provides useful energy storage through its built-in capacitance, and its ESR value is low enough to ensure reliable signal transmission. Whether used as a coupling capacitor or in power supply circuits, the R82DC3470DQ60K is a great choice for next-generation electronics.
