Film Capacitors – ECW-H12202JL Application Field and Working Principle

Film capacitors are one of the most widely used types of capacitors and are used in many applications. ECW-H12202JL is a film-type capacitor manufactured by EPCOS, a German company which produces a variety of electronic components. This particular capacitor is especially suited for use in small form factor applications that require a wide temperature range. In this article, we will explore the application field and working principle of the ECW-H12202JL.

Application Field

The ECW-H12202JL is a very versatile film-type capacitor that can be used in many different applications. This capacitor is designed to be used in environments with high levels of electrical noise or EMI, as it has a low EMI susceptibility which allows it to filter out electromagnetic interference. It can also be used in temperatures ranging from -55 to +125°C, so it is well suited for a variety of extreme use cases. Additionally, the ECW-H12202JL has a wide range of capacitance values which can range from 0.001uF to 0.022uF, which make it suitable for use in a wide range of applications including filtering, timing, and compensation.

The ECW-H12202JL is also well suited for space-constrained applications. It has a very small footprint and is only 2.5mm in diameter, making it suitable for use in small form factor applications. Additionally, its ESD rating of 5kV means that it is well-suited for use in high-voltage, high-frequency applications. All of these features make the ECW-H12202JL a great choice for many different applications.

Working Principle

The ECW-H12202JL is a dielectric film capacitor. This type of capacitor utilizes a plastic film as the dielectric material and two metal electrodes as the plates. This type of capacitor is known for its high stability, low EMI susceptibility, and low levels of self-inductance. Additionally, the plastic film is also highly desirable due to its low dielectric absorption and low electrical leakage, making it well-suited for various circuit applications.

In this particular capacitor, the dielectric material is a polypropylene film. The metal electrodes are made of tin-plated copper with a thickness of 0.08mm. Additionally, the capacitor is also coated with a conformal coating which helps to ensure its environmental performance is maintained over time.

The way the ECW-H12202JL works is that the two metal electrodes act as opposing plates. When a voltage is applied between the two electrodes, electrons will be accumulated on one plate and displaced from the other plate. This creates an electric field between the two plates which then stores energy in the form of a static electric charge. This charge can then be released when needed.

Conclusion

The ECW-H12202JL is a great choice for many applications due to its wide temperature range, low EMI susceptibility, and small form factor. Its dielectric material is highly durable and provides high levels of stability, and its small footprint is suitable for use in space-constrained applications. Additionally, its working principle allows it to be used for a variety of circuit applications.

Overall, the ECW-H12202JL is a great choice for many applications, from filtering and timing to high-frequency and high-voltage applications. Its various features make it suitable for a wide range of applications, making it one of the best film-type capacitors on the market.
