B32656S0125K561 Datasheet/PDFFilm capacitors are the main components in circuit designs, and are widely used in power supplies, power factor control units, inverters and other electronic products. The B32656S0125K561 is a film capacitor from EPCOS Group, a leader in the capacitor industry. This capacitor has a very wide application field, and it is also very reliable in terms of its working principle.
Application Field
The B32656S0125K561 is a high-voltage Film Capacitor. It has a rated capacitance of 0.0012 µF (12 nF) and a rated voltage of 500 V DC. This capacitor is designed for DC link or branch applications in power electronic circuits, particularly in their DC-link or branch input filter. It can also be used in power electronic output circuits such as photovoltaic converters, solar inverters, battery charging systems and other battery-operated devices.
Due to its high-voltage rating and low ESR (Equivalent Series Resistance), the B32656S0125K561 is an ideal choice for power factor correction devices, as it enhances the power factor of the relevant electrical device. This capacitor is also suitable for use in high-frequency circuits, as its reactive power is high compared to other types of film capacitors. Furthermore, this capacitor is also suitable for use in high-temperature environments, as its insulation system is designed to withstand temperatures up to 125°C.
Working Principle
Film capacitors are constructed from a thin plastic film, which is sandwiched between two layers of metal. The metal electrodes act as the two poles; the positive one being on the outer surface and the negative one on the inner surface. This sandwich construction allows the capacitor to hold a charge when a current is applied.
The charge stored in the capacitor is determined by the amount of electrical charge stored on each pole. In the case of the B32656S0125K561, the amount of charge stored on each pole is 0.0012 µF (12 nF). This amount of charge is determined by the size of the capacitor\'s capacitance.
When a voltage is applied to the capacitor, a current will flow and electrons will be stored in the capacitors. This creates an electric field across the capacitor, which allows electrical signals to be conveyed across the capacitor. This is the basic principle behind how the B32656S0125K561 works.
Conclusion
The B32656S0125K561 film capacitor from EPCOS Group is a reliable and highly efficient component. It has a wide range of applications in power electronics, power factor correction, high-frequency circuits, and high-temperature environments. As its rated capacitance is 0.0012 µF (12 nF), it can store a significant amount of electric charge when a voltage is applied. This makes it ideal for use in various applications. The working principle of this type of capacitor is based on the electric field created by the stored electrons.
