ECQ-E2273KF3

Film capacitors, also known as plastic film capacitors, are made of dielectric thin films. Polyester (PET, also known as Mylar), polycarbonate (PC, also known as Lexan), and polypropylene (PP) are commonly used as the dielectric films. These thin films are used to wrap metal electrodes to create the capacitor. The thin-film dielectric properties are closely related to the metal electrode structure, and the dielectric in the capacitor can store electrical energy. ECQ-E2273KF3 is one type of film capacitor.

ECQ-E2273KF3 is a radial-leaded paper capacitor with a temperature coefficient of +400PPM/C with a positive-tolerance up to ±10%, making it ideal for temperature-sensitive applications. It has a very wide operational temperature range of -25°C to +85°C, suitable for use in a variety of general-purpose applications. The structure of ECQ-E2273KF3 is made of a paper dielectric, a metal oxide film as the electrode, and a polymer case. The capacitor also has an internal electrode suitable for mounting on the printed circuit board, which eliminates the need for a separate mounting bracket. With its large capacity of 0.22μF, this capacitor is suitable for use in both low frequency and high frequency applications.

The working principle of ECQ-E2273KF3 is similar to other paper capacitors. It interacts with the electric current to charge and store electrical energy. When the capacitor is charged, an electric field is generated between the capacitor’s electrodes. This creates a potential difference across the capacitor, meaning that the capacitor can accept electric current from an external source or discharge electric current to another external source. The stored energy can then be used for various purposes.

ECQ-E2273KF3 is compatible with lead-free soldering, making it suitable for soldering processes used in high-end products. This capacitor is frequently used for frequency compensation, power supply filtering, high-frequency noise suppression, and more. ECQ-E2273KF3 is widely used in audio systems, high-end amplifiers, medical electronic devices, industrial drives, automotive electronics, electronic toys, and other electronic applications.

In conclusion, ECQ-E2273KF3 is a type of film capacitor that is constructed with a paper dielectric, a metal oxide film as the electrode, and a polymer case. It has a wide operational temperature range and large capacity, making it a suitable choice for many applications. ECQ-E2273KF3 is often used for frequency compensation, power supply filtering, high-frequency noise suppression, and more.
