Film Capacitors

Film capacitors are a type of capacitor that has an insulated film dielectric material that is rolled or folded, allowing them to be constructed in various shapes and sizes. They are typically found in consumer electronic equipment, and are found more frequently in modern circuits. They are available in two main types, one being Polyester (PET) Film and the other being Polystyrene (PPS) Film capacitors. However, one specific capacitor, the LDEPD1100KA5N00, is a type of Polypropylene (PP) Film capacitor.

Application Field and Working Principle

The application field of the LDEPD1100KA5N00 capacitor is relatively wide. The basic use of such capacitors is in DC link circuits, voltage divider panels in AC control circuits, high-frequency noise suppression coils, etc., and are generally not used for long-term energy storage devices. The working principle of the LDEPD1100KA5N00 capacitor is quite simple. An electric charge moves through a dielectric layer, with the two conductive layers on each side of the dielectric layer allowing the electrical current to be blocked and stored in the capacitor. This type of capacitor has a wide frequency range compared to other types, making it suitable for high-frequency applications; it has extremely low losses and excellent noise suppression, making it good for AC control applications. Some other common application areas for this capacitor include motor control, computer peripherals, voltage regulation, and audio systems. The LDEPD1100KA5N00 applicability in modern applications is such that it is used for suppression for up to 1GHz.

The exceptional performance of the LDEPD1100KA5N00 capacitor is due to the construction of its polymer dielectric. Unlike ceramic dielectric construction, in which a single ceramic determines the entire dielectric, the LDEPD1100KA5N00 uses multiple layers of polymer dielectric technology with a thin, thin layered thin-film plastic as the dielectric material, which allows it to achieve excellent mechanical and dielectric properties. This technology also provides a more accurate tolerance with minimal variation in capacitance over a wide range of frequency and temperature, which makes it the most suitable capacitor for the high-frequency technology. Furthermore, the polymer dielectric is highly resistant to aging and may be used over a longer period of time.

When applying the LDEPD1100KA5N00 in an application, heat dissipation is an important consideration. As with most capacitors, the LDEPD1100KA5N00 can distribute heat from its surfaces. This is generally due to ripple current, which is generated by the dielectric heating up during the application or when the circuit is switched from DC to AC, and is the primary source of power dissipation in a capacitor. The capacitor’s resistance to ripple current or heat will depend on the operating voltage and application. For example, if the operating voltage for the application is greater than the DC limit of the capacitor, then the capacitor will dissipate more heat when the voltage is applied. To reduce the effects of this, heat sinks with an adjustable cooling capacity may be used.

In summary, the LDEPD1100KA5N00 capacitor is an advanced and reliable capacitor, capable of handling high levels of voltage and frequency and is suitable for a variety of applications. It is especially useful in high-frequency applications because of its reliable performance characteristics, while its construction allows for reduced heat dissipation. Also, due to its wide temperature range, this capacitor can be used in temperature-sensitive applications.
