Film Capacitors

Film capacitors are extremely versatile components that provide a host of different electrical functions in a wide variety of applications. Referred to by different names such as metallized polyester or polypropylene film capacitors, they are commonly used in both mains and low voltage circuits. Their most common uses are as filter capacitors and pulse bypassing capacitors.

B25620B1117K321 Application Field and Working Principle

The B25620B1117K321 is a metallized polyester capacitor used mainly in pulse bypassing and power supply applications in high frequencies. It is designed to work with a wide range of frequencies and temperatures, making it well-suited for a variety of uses.The B25620B1117K321 is composed of two parallel pieces of metallized polyester film with a dielectric layer in between, including the termination leads. This structure helps store electrical energy under an applied voltage, or as reversed, can release electrical energy when the voltage is applied in the opposite direction. This process makes it suitable for use as a pulse bypass capacitor.When the capacitor is connected in series to an AC supply, the electrical field between the capacitors plays an important role in its operation. When an AC voltage is applied, the electrical field present between the plates attracts both the positive and negative charges. The resulting charge accumulation is the process known as capacitance. Over time, the charges accumulate and eventually reach a maximum level, or a maximum capacitance, determined by the dielectric values of the electret components.Furthermore, the B25620B1117K321 is able to offer great performance as its dielectric constant is very low, making it very reliable for high frequency applications. Additionally, it has a very low stiffness of the electric field, which means that it helps to reduce loss and power consumption.The B25620B1117K321 is also highly corrosion-resistant thanks to its electroplated coating on both sides of the metallized film. This type of coating makes the capacitor more reliable and durable, and allows it to offer superior performance.In conclusion, the B25620B1117K321 has many advantageous features such as its low dielectric constant and its corrosion-resistant coating, which make it suitable for use in pulse bypass and power supply applications in high frequencies. Its small size also makes it easy to use in low-cost applications without compromising performance.
