Film Capacitors

Film capacitors are widely used for a variety of applications in electronic circuits. They are constructed from two conductive surfaces (electrodes) separated by a dielectric layer. The electrodes are typically very thin films of metals deposited on a substrate, either glass or plastic. The dielectric layer can be made from a range of materials, including Mylar, Kynar, and Teflon.The 155PPA850K is an example of a film capacitor, typically used for power factor correction (PFC) applications. It is a non-polarized capacitor, meaning the polarity of the leads does not matter when connecting it in a circuit. This type of capacitor offers very low ESR (equivalent series resistance) and a very wide frequency range, making it ideal for use in power supplies used in switched mode power application.The working principle of a film capacitor is based on capacitance. When a voltage is applied to a capacitor, the charges stored on the electrodes are balanced out, creating an electric field. This electric field creates a charge on the dielectric layer which acts as a buffer, allowing the capacitor to store a charge on both its plates. As the voltage is increased, the capacitance of the film capacitor also increases, creating a better insulation between the plates.The 155PPA850K is designed to absorb the harmonic distortion caused by the switching of pulses in the power supply. By increasing the capacitance, the capacitor is able to absorb more energy and reduce the amount of distortion in the signal. It is also used to smooth out the current in the circuit, allowing a steady supply of power to be provided to the load.When used in power supplies, film capacitors are typically connected in parallel with other components, such as diode rectifiers, to provide the smoothing effect. They are also commonly used in the secondary of a transformer. The 155PPA850K can be used for single-phase PFC applications, back-to-back PFC applications, and for PFC applications with paralleled active components.Overall, film capacitors are used in a variety of applications such as power factor correction, filtering, signal conditioning, snubber circuits, and surge protection. The 155PPA850K is an example of a film capacitor designed for PFC applications, allowing for a steady supply of energy and reducing harmonic distortion in power supplies. Its low ESR and wide frequency range makes it suitable for most switching mode power applications.
