Film capacitors are widely used in audio-frequency, radio-frequency, and power electronic circuits. Capacitors, or condensers, are electrical components used to store and regulate electric current. By applying a voltage across the two terminals of a capacitor, electric charge can be stored. Similarly, when the two terminals are disconnected, the stored electric charge is instantly discharged. Film capacitors are constructed using thin plastic film as the dielectric, for which the plastic must be chosen with a high dielectric strength. These capacitors can handle a great amount of voltage and have a very low leakage current, making them ideal for use in high stability applications.

The B32642B0683J is a particularly advanced series of film capacitors from the B32642 family from EPCOS. This series has capacitances ranging from 0.01 µF to 0.68 µF, which makes it particularly suitable for applications in the audio-frequency range and power electronic circuits. The high insulation of the plastic film reduces the leakage of electric current and allows the capacitors to achieve excellent long-term stability. Due to these advantages, the B32642B0683J is commonly used in applications such as power inverters, audio/video systems and medical imaging systems. In addition, they are also suitable for applications like motor drives and electric vehicles.

To understand the working principles of the B32642B0683J capacitors, it is necessary to first understand the basic structure of a capacitor. A typical capacitor consists of two conductive plates, separated by an insulating material, known as the dielectric. When a voltage is applied across the two plates, an electric field is generated, which causes electric charge to be stored on the plates. This stored charge creates an energy field within the capacitor and forms an electric double layer. This electric double layer provides the capacitance of the capacitor, which is measure in Farads.

The B32642B0683J capacitor is constructed using aluminum foil as the external plates and a plastic film as the dielectric. This plastic film has a very high dielectric strength, which enables the capacitors to store a very large amount of charge and handle a great amount of voltage. In addition, this plastic film also provides a very low leakage current, allowing the capacitors to achieve a long-term stability. These B32642B0683J capacitors are typically mounted onto printed circuit boards (PCB) using a variety of mounting methods, such as through-hole, surface mount and socketed.

In summary, the B32642B0683J is an advanced series of film capacitors from the B32642 family from EPCOS. This series of capacitors is most commonly used in audio-frequency, radio-frequency and power electronic circuits. The capacitors are constructed using aluminum foil as the external plates and a plastic film as the dielectric, which provides a very high dielectric strength and extremely low leakage current. These features make the B32642B0683J ideal for use in applications such as power inverters, audio/video systems and medical imaging systems.
