Film capacitors are capacitors with a dielectric film created from homogeneous plastic materials. They are primarily used in power factor correction applications and in voltage filtering, smoothing, and power supply decoupling applications. Foremost among film capacitors is the ECW-FD2W684K series. In this article, we will explore the application field and working principles of ECW-FD2W684K film capacitors.

Application Field

The ECW-FD2W684K series are designed for use in electronic circuits which use voltages of up to 1kV, and operating frequencies up to 10kHz. They can also be used in AC and DC circuits, making them a popular choice for engineers who need to work with both types of power sources. Furthermore, they are also popular in transient suppression applications, as they are able to withstand high ripple currents without any operational issues.

The ECW-FD2W684K series can also be used in power factor correction, rectifier circuits and in energy storage applications. Due to the high voltage and operating frequency ratings, they can be used in a variety of industrial applications, medical equipment and motor drives. Additionally, their wide range of temperature ratings make them suitable for use in high temperature environments.

Overall, the ECW-FD2W684K series are capable of handling immediate and short-term surges, as well as prolonged operation in circuits with high load currents. Their compact and reliable design also makes them a favorite choice for use in small but critical components of electronic circuits.

Working Principle

Film capacitors use a dielectric film made of homogeneous plastic materials (often polypropylene or polyethylene-naphthalate) as their dielectric. When a voltage is applied between the two electrodes, an electrostatic field is formed between them. This electrostatic field causes the electrons in the film to move, creating an electric charge. This is the underlying working principle for film capacitors.

The ECW-FD2W684K series are capable of handling high voltages and ripple currents better than many other capacitors. This is due to the high-quality metallized polypropyrene dielectric used in their construction. This special dielectric material has exceptionally high dielectric strength and excellent heat resistance. As a result, the ECW-FD2W684K can withstand high voltages and high frequency ripple currents without losing their capacitance or having any additional losses.

In addition, the ECW-FD2W684K series are available in a compact housing, which makes them an ideal choice for high-density circuits. Their compact size also allows them to be used in limited space applications. Furthermore, their design is also resistant to vibration, making them suitable for use in mobile and industrial equipment.

Overall, the ECW-FD2W684K series are high-quality film capacitors, designed for high voltage and high frequency applications. Their ability to handle high voltages and ripple currents make them a popular choice for engineers working with circuits with stringent requirements. Their compact size and vibration resistance also make them ideal for use in a variety of applications.
