Film Capacitors

Film capacitors, also known as polyester film capacitors, are a type of capacitors that uses a polyester film or polypropylene film as the main dielectric material. The ECQ-E10563KFB is a polypropylene film capacitor that belongs to this category.

Application Field

The ECQ-E10563KFB has a number of uses, first and foremost in high frequency applications. This is due to the fact that the polypropylene film it is made of has very low internal losses and dielectric absorption. The great thing about purchasing this type of capacitor is that it is also incredibly useful for high voltage applications as it contains PET polyester film and is typically filled with water-based dielectric fluids, which help reduce the insulation resistance as well as increase the overall capacitance of the device.

In addition to these extraordinary capabilities, the ECQ-E10563KFB is capable of being used in a variety of circuits, including timers, inverters, amplifiers, and many types of dc circuits. It is particularly suitable for use in high-end audio equipment and is an excellent choice for powering speakers.

Working Principle

The ECQ-E10563KFB works in a similar fashion to other capacitors. When electric current is applied to the capacitor, an electric field is created between the two plates due to the electrostatic effect. The relative dielectric constant of the film acts as a dielectric between the two plates, causing a "current blocking effect". This is the same principle used in most capacitors.

The unique feature that sets the ECQ-E10563KFB apart from other film capacitors is its low internal losses. This is due to the polypropylene film it is made out of, which has a low dielectric absorption and low series resistance. As a result, it is perfect for high frequency applications such as power conditioning and signal filtering.

Overall, the ECQ-E10563KFB is an outstanding choice for high voltage, high frequency, and power conditioning applications. Thanks to the properties of its polypropylene film, it is able to provide smooth and stable performance.
