Film Capacitors

Film capacitors have emerged as a mainstream electronic component for a range of applications due to their high capacitance density, excellent nonlinearity over temperature, and high frequency and voltage ratings. The technology has found numerous applications in power electronic tasks involving high voltage and high charge or energy such as ultra sonic, high voltage switching, high power PFC rectifiers, and drives. Among these capacitors, the JS211156-AA is one of the most popular film capacitors in the market.

JS211156-AA Application Field and Working Principle

The JS211156-AA capacitors are designed for a variety of applications. They are suitable for applications involving high voltage, high charge or energy, and ultra sonic signals. These capacitors can also be used as a filtering, and energy storage elements in parallel with an inductor to handle the highest inrush current in a power unit. The operating frequency determines the number of capacitors required to be connected in parallel to achieve the desired performance. This ensures that the input current remains low and the inductance remains limited.

The working principle of the JS211156-AA film capacitor is based on Faraday’s law. The capacitor is made up of two electrodes, a positive and a negative, that are separated by an insulating material or film. The electrodes are covered in a special dielectric that allows them to be electrically connected to the power source. As the voltage between the electrodes changes, a certain amount of charge is stored. This charge is called the capacitance, and the time constant is the amount of time required for the charge to be discharged or released.

The film capacitors have superior reliability and stability in the presence of temperature, vibration, and frequency variations. The main reason for this is that the dielectric material used in their construction is highly resistant to fatigue and environmental stress. The film capacitor is also self-healing, meaning that any shorts or breaks that develop in the dielectric layer and electrical terminals can be provoked by storing energy which will cause the electrodes to form a hole in the film preventing further shorts of breaks.

The film capacitors have only moderate dielectric absorption, which means that they require less energy to store and release energy than other types of capacitors. Additionally, the dielectric constant of the films used in their construction is usually higher than other capacitors. This means that the capacitance of the film capacitor is usually higher than any other type of capacitor. This makes the JS211156-AA a great choice for applications requiring high capacitance.

The JS211156-AA film capacitor is also designed to provide various current and power ratings. It has a maximum working voltage of 1500VDC and can withstand up to 2000VAC. The rated capacitance of the capacitor is 0.15µF, which makes it suitable for applications with moderate current demands.

The JS211156-AA film capacitor is a popular choice in the industry due to its excellent performance, wide range of applications, and superior reliability. The good performance and long lifespan of the film capacitor make it an ideal choice for applications in a range of industries including aerospace, computer, medical, automotive, and consumer electronics.
