Film Capacitors

A film capacitor is a type of capacitor constructed with a thin plastic film as the dielectric. It is most commonly used in radio frequency applications, because of its excellent high frequency characteristics and small physical size. LP385336025JBI2B0 is a film capacitor that use a Thin Film Metallized Polypropylene (TMMP) as the dielectric material, constructed in cylindrical shape.

Application Field

LP385336025JBI2B0 capacitors are capacitors specifically designed for automotive, industrial and professional audio applications. They find application in various pulse current circuits as well as AC circuits, particularly those operating in a wide temperature range of -40℃ to +105℃. Moreover, they are ideal for electronics, such as motor control systems, DC-DC circuits, measurement equipment, telecom systems and automotive systems.

Working Principle

Film capacitors are constructed by dielectric films, such as polypropylene, with metal electrodes on both sides of the film. The electrodes are usually either aluminum or zinc. When the electrodes and films are arranged, the capacitor can store electric charges. When a voltage is applied, these electric charges are induced on the metal electrode and accumulate. This accumulation of charges allows electric current to flow between the metal electrodes, allowing the capacitor to be used in both AC and DC circuits. In general, the thicker the dielectric film and the larger the metal electrodes, the higher the capacitance of the capacitor.

LP385336025JBI2B0 capacitor has a dielectric thickness of 0.5mm, a dielectric constant of 1.01 and a rated voltage of 250V. The metal electrodes are made of aluminum and are 0.5mm thick. This combination of material, size and capacitance makes it perfect for use in automotive, industrial and professional audio applications.

Another important aspect of LP385336025JBI2B0 is its ability to dissipate heat. The metal electrodes and thin dielectric film allow the capacitor to dissipate heat more effectively than other types of capacitors, such as electrolytic capacitors. This makes it ideal for use in high frequency applications, where the capacitor is exposed to large amounts of current.

Conclusion

The LP385336025JBI2B0 capacitor is an excellent choice for automotive, industrial and professional audio applications. Its thin film dielectric and large metal electrodes allow it to have a high capacitance, while its ability to dissipate heat makes it ideal for high frequency applications. It is one of the most reliable and versatile film capacitors on the market.
