Film Capacitors

Film capacitors are passive components used to store electrical energy in an electric field. They are constructed using thin dielectric film layers with interleaving metal electrodes, and the dielectric film materials can affect the capacitance, stability, and dissipation factor of the capacitor. Film capacitors are widely used in electronic circuits due to their high reliability, high capacitance retention performance, low self-inductance, and long service life. Film capacitors are made in various voltage ratings, dielectric materials, and physical sizes.

B32620A6152K289 Application Field and Working Principle

The B32620A6152K289 is a polypropylene film capacitor made by EPCOS, one of the world\'s leading capacitors manufacturers. As an axial format film capacitor, this device features an operating voltage of 630VDC, a capacitance value of 0.15uF, and a 5% tolerance rating, making it suitable for filtering, decoupling, snubber, and bypass circuits. The polypropylene material used in this device makes it appropriate for usage in high frequency circuitries, particularly in electronic equipment requiring high performance and excellent frequency characteristics.

The working principle of the B32620A6152K289 lies in its metallic electrode layers separated by a dielectric film. When an electrical voltage is applied to the capacitor, a surface electrical field is created between the electrodes, and charge begins to be stored in the capacitor, forming an electric field. This electric field, which is the capacitor’s energy storage, is proportional to the applied voltage and the capacitance of the capacitor. When the applied voltage is removed, the electric field collapses and the stored energy is released as a sustained current.

These characteristics make the B32620A6152K289 ideally suitable for use in electronic equipment, computer mainframe, power supply, and other applications operating in high frequency, high temperature, and low current environment. Additionally, the polypropylene material gives this capacitor excellent electrical properties, making it suitable for use in high temperature circuits, such as high power, high frequency, and AC circuits. The B32620A6152K289 is typically used as an energy storage and filtering device in many applications. Its small package, high capacitance density, and excellent reliability makes it one of the most commonly used polypropylene film capacitors in the world.
