Film Capacitors

Film capacitors are a type of capacitor that use thin film as the dielectric and consist of two separated electrodes. They are commonly formed by winding two plain dielectric films dielectrically isolated from each other to form an encircling winding of two-layer thin-film capacitors. Film capacitors are often used in a variety of electronic circuits and devices as they feature low losses, high stability and high temperature capability. Film capacitors can also be constructed to act as high voltage components that can handle higher voltages than other capacitors.

The 184472J400RAA-F is a film capacitor and acts as a high voltage capable, low loss, and high temperature capacitor in electronic circuits. This capacitor has a thin film dielectric and is suitable for power factor correction and voltage motor start-ups that require a large high voltage capacitor range. The 184472J400RAA-F has a working range of 0.85 up to 75 kV, a capacitance value of 0.47-47 µF, and a working temperature range of up to 125° C.

The 184472J400RAA-F utilizes a dielectric layer which allows the storage of electric charge between two conducting plates which are precisely separated by an insulator material. The electric charge can be stored and released, thus acting as an energy storage or battery. When there is a source of electrical energy, the capacitor charges up and the stored energy increases. The voltage across the plates continues to increase until it reaches the maximum voltage rating of the capacitor.

When the voltage is removed, the capacitor releases the stored energy and the stored charges drain from the capacitor. The rate of discharge or relaxation of the capacitor depends on the capacitance value and the amount of current that the capacitor can produce. The rate of discharge of the capacitor also depends on the frequency of the alternating current.

In addition to capacitance and voltage, the performance of the capacitor also depends on the series resistance and inductance which can create additional losses. The impedance of the capacitor is also influenced by the internal temperature, which affects the capacitance and effective series resistance.

The 184472J400RAA-F is a high voltage capacitor which is designed for power factor correction and voltage motor start-ups.
