Film capacitors, also known as plastic film capacitors, are constructed out of two layers of plastic film coated with metal electrodes and surrounded by a dielectric coating. Depending on the type of plastic film used and the type of dielectric, such capacitors can be used in many varied applications including audio, power electronics, automotive and medical equipment. The 940C12P22K-F capacitor is a specific type of plastic film capacitor designed for a variety of industrial applications.

The 940 series of capacitors by EcoE has a temperature coefficient of -22,000 ppm/K and it is available in a variety of styles from 5.5V to 100V. The 940C12P22K-F capacitor specifically has a working voltage range of 12V. It is also available in a radial leaded or surface mount package and can handle high levels of ripple current due to its high resistance. The 940C12P22K-F capacitor is a polyester-based dielectric film which provides the highest stability, reliable performance and improved high frequency recording.

Since the 940C12P22K-F capacitor is constructed out of polyester film, it is ideal for high frequency applications, resulting in reduced electrical noise, improved interference rejection and low signal distortion. Its low ESR also ensures a reduction in overall device power consumption and thermal dissipation. This makes it a suitable choice for applications where energy efficiency is paramount. The 940C12P22K-F capacitor is also well-suited for use in medical, automotive and audio equipment due to its wide temperature range, excellent stability, and long-term reliability.

The 940C12P22K-F capacitor’s most important feature is its ability to handle ripple currents at high temperatures. This is achieved due to its low series resistance (ESR) and high-temperature stability. This is especially beneficial for applications such as electric vehicles and renewable energy systems, where this capacitor can help reduce the system’s electrical noise and prolong its lifespan in temperature extremes. Moreover, it is UL 94V-0 approved, ensuring its reliable performance in harsh environmental conditions.

The 940C12P22K-F capacitor’s working principle is based on the electrostatic property of electricity; where two layers of plastic film coated with metal electrodes are separated by a dielectric coating. This creates a region of electrical stress known as the dielectric field. The dielectric field is responsible for storing electrical energy which is released when there is a sudden decrease in voltage or current demand. This is how the film capacitor works in applications like audio devices and medical equipment, where it provides a smooth and continuous power supply even in cases of sudden load fluctuations.

Overall, the 940C12P22K-F capacitor is a high-performance capacitor that is suitable for a variety of industrial applications. It features low ESR and excellent temperature stability, good ripple current handling, and is UL 94V-0 approved. In addition, its electrostatic properties and high frequency application make it an ideal choice for audio and medical equipment. All of these features make the 940C12P22K-F capacitor an excellent choice for industrial applications where reliability and efficiency are essential.
