Introduction to Film Capacitors
A film capacitor, also known as a film dielectric capacitor, is a type of capacitor that typically uses a plastic film as its dielectric. It also has metal electrodes that are enclosed in a thin film layer. The thickness and type of film material used determine the capacitance value required in each application. Film capacitors are usually made from polycarbonate, PET, polyester, polyimide, polysulfone, and polyphenylene sulfide (PPS) depending on the type of application. The construction of the film capacitor is much more complex than the standard electrolytic capacitor. Due to their superior characteristics, film capacitors are widely used in high frequency, high voltage, and power supply applications.733P334X9400 Application Field and Working Principle
The 733P334X9400 Film Capacitor, manufactured by AVX Corporation, is a AC/DC film capacitor with high accuracy and low loss. This capacitor features a high capacitance per unit volume, making it ideal for applications where space is limited. This capacitor is most often used in AC and DC circuits, such as power supplies, inverters, UPS, EMI/RFI filters, and more.The working principle of the 733P334X9400 Film Capacitor is based on electrical energy stored in a dielectric layer called a barrier or insulating layer. This barrier is placed between two plates which are polarized (have a positive or negative charge relative to each other). The positive and negative charges attract each other, which creates an electrostatic field. When current passes between the plates, the electrostatic field experiences an increase in energy. This energy is then stored in the capacitor, and can be released again when the current is reversed.Advantages and Disadvantages of Film Capacitors
One of the main advantages of using film capacitors as opposed to other types of capacitors is their low resistance. This makes it possible to construct smaller capacitors with higher capacitance without sacrificing power. In addition, film capacitors don’t suffer from dielectric absorption, eliminating the need for periodic rearrangement of dielectric layers. This eliminates the need to test and verify dielectric characteristics, which can save time and money.Film capacitors also feature a wide DC voltage range, compared to other types of capacitors. This makes them suitable for applications with large pulsed current or wide input voltage ranges.However, there are a few drawbacks to using film capacitors. Film capacitors tend to be more expensive than other types of capacitors, and are generally not suitable for high-temperature applications due to their limited temperature range. In addition, film capacitors may not be as robust as other types of capacitors, and may experience some aging over time.Conclusion
In conclusion, the 733P334X9400 Film Capacitor from AVX Corporation is an AC/DC film capacitor with high accuracy and low loss. This capacitor is ideal for applications where space is limited, and is most commonly used in AC and DC circuits, such as power supplies, inverters, UPS, EMI/RFI filters, and more. Film capacitors feature many advantages over other types of capacitors, including low resistance, wide DC voltage range, and low dielectric absorption. However, they can also be more expensive and may not be as robust or able to handle high temperatures as other types of capacitors.
