Film Capacitors
A film capacitor (or plastic film capacitor, or film dielectric capacitor) is an electrical capacitor with a dielectric made of a thin plastic film. It is constructed like a common non-polarized electrolytic capacitor, but employs a film instead of paper or wet electrolyte as the dielectric. Non-electrolytic capacitors are typically impregnated in some way to avoid delamination of the electrodes and dielectric. The use of metallized layers, the most common realization of the electrode, allows for extremely low equivalent series resistance (ESR) and thus highly efficient power dissipation.
185333K250RCA-F Application Field and Working Principle
Film capacitor (also known as a “Polyfilm”, “Polypropylene Capacitor” or just simply “Film Cap”) 185333K250RCA-F is an ultra-high voltage film capacitor designed specifically for high voltage applications with a breakdown voltage of 250V AC. It utilizes the latest technology in polymer film which allows it to achieve extremely low leakage current and high performance for high voltage applications. The 185333K250RCA-F is often used as a power factor correction capacitor for high voltage applications where space is limited.
For the working principle, this type of film capacitor combines two metallic plates fixed to a dielectric material of a polyester film. As the electric field created by the charged metal plates builds, the electrons in the film respond by aligning in the same direction; this phenomenon is also known as polarization. As the electron alignment increases, the capacitance value increases. When the applied voltage is high enough, the electric field builds to a point where the strength of the dielectric breaks down, causing a charge to inject into the dielectric and form a ”snap-off” charge. This snap-off causes a corrosion of the metal electrodes over time.
Another important factor when considering the working principle of this type of film capacitor is the self-healing property. When the self-healing property is activated, the charge injected into the dielectric initiates a curing process that heals the damaged area and reacts to the applied voltage. This process gradually heals the area over a period of time, restoring the performance levels to original specifications without the need for any repair or replacement.
Conclusion
In conclusion, 185333K250RCA-F is an ultra-high voltage film capacitor designed specifically for high voltage applications. Its key characteristics include extremely low leakage current and high performance for high voltage applications, and the self-healing property which ensures the capacitor will perform up to specifications and not require any repair or replacement. It is often used as a power factor correction capacitor for high voltage applications where space is limited.
