Film capacitors are electrical components used to store energy many applications such as noise filtering, signal conditioning, power conditioning, and power supply smoothing. The ECQ-E2105KS series film capacitors are designed for AC line filtering, snubbers, and power supply applications. This article will explain the application field and working principle of the ECQ-E2105KS series.

Applications

The ECQ-E2105KS series is a type of non-inductive, self-healing film capacitor manufactured by Epcos. It\'s designed to meet the requirements of AC and DC mains EMC filtering, as well as applications in motor control, such as cable shielding in elevators and snubbers in switch-mode power supplies. It is also suitable for energy storage applications like bank capacitors, over-voltage/under- voltage protection, and power factor correction.

Features

The ECQ-E2105KS series film capacitors offer several advantageous features that make them one of the most reliable and efficient components. The series has a high dielectric strength and large capacitance tolerance, which makes them ideal for a range of demanding applications. The series also features high ripple current capability, allowing it to handle a range of high-frequency noise. Additionally, its low equivalent series resistance values make it suitable for many high-frequency filter applications. In addition, the capacitor is self-healing and can withstand up to 2,500V AC/DC.

Working Principle

The working principle of the ECQ-E2105KS film capacitor is based on the relationship between current and voltage. The capacitor stores electrical charges when the voltage is applied across its terminals. This electrical charge creates an electric field within the device and allows the capacitor to store energy. When the applied voltage is unbalanced, the capacitance of the device decreases, resulting in a decrease in electric field strength and a decrease in current. The decrease in current will result in the device being unable to store energy efficiently.

The ECQ-E2105KS series also employs self-healing technology. When a voltage spike occurs, the device can sense the short-lived overload and reduce the amount of current flowing through the device. This increase in resistance helps to reduce the spike, which prevents further damage. This feature also helps to reduce overall power losses and improve efficiency.

Conclusion

The ECQ-E2105KS film capacitor is an efficient and reliable electrical component that is suitable for a range of EMC filtering, motor control, and energy storage applications. Its features include a high dielectric strength, large capacitance tolerance, and low equivalent series resistance. Additionally, it utilizes self-healing technology, which helps to protect it in the event of voltage spikes. This article has explained the application field and working principle of the ECQ-E2105KS film capacitor, and demonstrated why it is suitable for many demanding applications.
