Film Capacitors

Film capacitors, also known as polymer film capacitors, plastic film capacitors, film dielectric capacitors, are components of electrical capacitors which use a film as the dielectric / insulating layer. They are constructed similarly to other types of capacitors but instead of the dielectric being an electrolyte or ceramic, it is a thin plastic film. The film capacitors used in most applications today are in the form of rectangular Teflon, polypropylene, or polystyrene capacitors.

ECH-S1H224GZ

The ECH-S1H224GZ Film Capacitor is a surface-mount capacitor designed for use in various applications. With a rated voltage of 16 VDC, this capacitor is capable of withstanding high temperatures up to 125°C and high current density. It is a Non-polarized film capacitor, which has excellent self-healing properties, making it a great choice for critical applications.

Application Field

The ECH-S1H224GZ Film Capacitor is most often used in high-end, precision electronic circuit designs of various types. Its non-polarity and high capacitance make it ideal for use in high-frequency, high-performance circuits, such as in RF amplifiers, systems, imaging systems, and biomedical equipment, just to name a few. The device is also recommended for power supplies, power conversion circuits, and communication circuits.

Working Principle

The Plate Capacitor, also called a paper capacitor, has two main working principles.

• The first working principle is the storage of electric charge within a dielectric layer in order to create an electric field. When two or more conductive electrodes are placed on either side of a dielectric layer, they are connected electrically and the electric field created by the electrical charge is capable of storing energy.
• The second working principle is the ability of the film capacitor to block the flow of direct current while allowing the passage of high-frequency alternating current. This makes them invaluable in certain applications where the low-noise electrical filtering of high-frequency signals is required.

Conclusion

The ECH-S1H224GZ Film Capacitor is a highly versatile, low noise, non-polarized film capacitor ideal for high-precision, high frequency, and power conversion applications. It is capable of withstanding high temperatures and high current densities, making it ideal for harsh and critical applications. Its ability to store electrical charge within a dielectric layer and to block the flow of direct current while allowing the passage of high-frequency alternating current make it a valuable device for high-performance electronic circuit designs.
