Film capacitors, or plastic film capacitors, are among the most versatile types of capacitors. These components are made of a polymer thin film, with a conductive film layer applied over it. The two materials are wound tightly together in the presence of alternating current, creating an electrostatic field between them. The resulting electric field helps to control the electrical current which flows through the device.

A film capacitor with the part number DPFF12D47J is designed mainly for power supply filtering and suppression applications in industrial, automotive and the renewable energy sector. This type usually comes in an axial type package. It features a flat, radially symmetrical electron field with high-insertion loss performance, providing an EMI snubber-like effect. Thus, it used in filtering and suppression of noise and interference in the power supply line.

The DPFF12D47J is an Automotive Grade capacitor that can operate in high temperatures up to 125°C. Additionally, it provides a high dielectric strength with a very low dissipation factor, making it ideal for automotive and industrial applications. Because of its high capacitance and low-impedance features, it is also applicable in line-filter power converters, automotive audio systems, digital radios and solar inverters.

The working principle of a film capacitor is relatively simple. A thin polymer film is used as the dielectric material between two dielectric electrodes. The two electrodes create an electric field that causes the capacitor to store a charge.When a source of electric energy is applied to the electrodes, charge begins to move across the two electrodes, creating an electric current. The resulting electric current is then used to power or actuate a device, depending on the desired application. The charge stored on the capacitor will remain until it is discharged through a short circuit or discharged by connecting a load.

Film capacitors are usually polarized, meaning that they must be installed correctly in order to work properly. If installed incorrectly, the capacitor may experience a high amount of power loss, or the electric current may not flow at all. For this reason, caution should be taken when installing polarized film capacitors.

Film capacitors are widely used in many different applications, such as filtering, energy storage, signal coupling, and voltage regulation. Thanks to their low-cost, high-efficiency, and reliable performance, they have become a popular choice for many different applications. In addition, they are known for their low self-inductance, low temperature coefficient, and their high breakdown voltage.

Film capacitors, such as the DPFF12D47J, are found in a variety of applications, ranging from high-end electrical equipment to consumer electronics. They are designed to provide reliable operation and offer superior performance in a wide range of electrical and environmental conditions. They can be used as filters, energy storage devices, power factor correction, and more.
