Film Capacitors

Film capacitors are non-electrolytic capacitors that use plastic film as the dielectric. Film capacitors are diverse in both design and applications. Through the selection of different materials and layering methods, a wide range of electric characteristics can be achieved. Furthermore, film capacitors can accommodate large voltage ranges, high current levels, and a wide range of temperatures. The two most common types of film capacitors are polyester and polypropylene.The MPX333K305D is a film capacitor designed to bridge the gap between regular film capacitors and high-performance power film capacitors. With a maximum operating temperature of 115°C, it offers more stability and reliability than standard film capacitors. Furthermore, MPX333K305D offers high voltage ratings and high insulation resistance and is suitable for a broad range of electronics with both commercial and military applications.

Application Field

The MPX333K305D capacitor is suitable for a wide range of applications, including commercial and military applications. It is mostly used in power supplies, line filters, bypass circuits, and coupling and decoupling circuits. It is also suitable for high-temperature, high-voltage and high-power circuits such as electronic ballasts, HID lamps, PFC circuits, UPS systems, AC/DC converters, and inverters. The capacitor can also handle over-voltage and short-circuit conditions, guaranteeing excellent temperature stability and long life.

Working Principle

The MPX333K305D works by using a thin film of heat-resistant polymer as the dielectric. The film acts as an insulator and prevents the capacitance from changing due to external factors such as temperature and voltage. The primary advantage of using a film as the dielectric is that it provides superior insulation characteristics compared to other types of capacitors such as ceramic and aluminum electrolytic capacitors.In addition to its insulating properties, the film in the MPX333K305D also offers exceptional temperature stability and high dielectric constant. The dielectric constant of the film determines the capacitance of the capacitor and is highly temperature-stabilized. This allows the device to operate over a wide temperature range while maintaining a consistent capacitance value.Overall, the MPX333K305D is an excellent choice for applications that demand high reliability and a long lifetime. With its exceptional temperature stability and high insulation resistance, the device is ideal for high-voltage applications and can handle temperature and voltage extremes. Its high surge current capabilities and over-voltage protection capabilities make it a reliable and efficient choice for many commercial and military applications.
