It is widely used in circuit boards as bypass capacitors, energy storage capacitors, interference suppression capacitors and etc. FCP0805H391G-J1 has high temperature resistance, wide working frequency range, low impedance and low insertion loss features.

Working Principle: A film capacitor, also known as a dielectric capacitor, is an electrical device composed of two electrodes separated by a dielectric film material. The properties of the film capacitors depend on the dielectric material and the size of the electrodes. When a voltage is applied to the capacitor, a certain electrical field is created within the dielectric material, which affects the charge distribution of the plate electrodes.

The working principle of FCP0805H391G-J1 is based on the above mentioned principle. Its dielectric material is made of polyester film, which has excellent properties such as high insulation resistance, low capacity and low loss tangent. And the size of the electrodes is designed to be relatively small to ensure its high frequency performance. Under the action of the electrical field, electrons transfer from one electrode to another and the resulting electric current and magnetic field help to extract energy from the capacitor\'s terminals, thus storing energy in the capacitor.

In conclusion, FCP0805H391G-J1 is a kind of film capacitors and its application fields are industrial power supplies, camera strobes, laptop power supplies and other power circuits. The working principle is based on the action of the electrical field. Its dielectric material is made of polyester film and the size of the electrodes is designed to be relatively small to ensure its high frequency performance.
