Film capacitors, a type of electronic component, technology and category are being used in various applications. These capacitors are usually made from polyester or polypropylene materials. Film capacitors are usually used to store energy in electrical devices, stabilize voltage and filter RF signals, among many other uses. Here, we will discuss the ECQ-U2A564ML, a film capacitor that falls into this category, and its application field, as well as its working principle.

Capacitors Basics

In order to understand the ECQ-U2A564ML, it is helpful to first review some basics of capacitors in general. A capacitor is a component of an electrical circuit, consisting of two metal plates that are separated by an insulating material also known as a dielectric. When a voltage is applied to the capacitor, it accumulates electric charges of opposite polarity on its adjoining plates, and once charged, the capacitor acts like an energy storage device, distributing and storing charge in the electric field in the dielectric generated by the applied voltage. The voltage and current in the capacitor are inversely proportional, meaning as one increases, the other must decrease.

ECQ-U2A564ML Film Capacitor

The ECQ-U2A564ML is a film capacitor specifically designed for AC power automotive applications. It has a 48mm diameter with a capacitance range of 0.22μF to 4.7μF. The ECQ-U2A564ML is a self-healing type capacitor that prevents low-frequency signals from passing through due to its high ripple current absorption capacity. It is also able to withstand up to 5kV AC voltage and 85°C maximum operating temperature.

Application Fields

The ECQ-U2A564ML has a variety of potential application fields. It is used in filter circuits, power factor correction, and other kinds of electronic equipment to generate large amounts of current. As stated above, it is designed for automotive applications, but can also be used in industrial, communication and medical equipment for energy-saving purposes or for measurement purposes, such as providing electrical power for accuracy and precision control.

Working Principle

The ECQ-U2A564ML works on the same principle as other film capacitors. As voltage is applied to the capacitor, electrons flow from one plate to the other, building up an electric field in the dielectric that is produced by the plates. As charge accumulates on each plate, an imbalance of the electric potentials begins. The dielectric material between the plates is there to prevent the flow of current across the capacitor, thus accumulating and storing energy. When the voltage is removed, the stored energy is then released back into the circuit as current.

Conclusion

The ECQ-U2A564ML film capacitor is an excellent choice for AC power automotive applications. Designed with a high ripple current absorption capacity, it is able to withstand up to 5kV AC voltage and 85°C maximum operating temperature. It is also a self-healing type capacitor, preventing low-frequency signals from passing through. Additionally, the ECQ-U2A564ML can be used for energy-saving or measurement purposes in many other applications.
