Mica and PTFE capacitors are types of capacitors which are specially identified by their dielectric material. The CM04ED390JO3 is one of the capacitors that belongs to this family. Specifically it is a radial dipped multilayer ceramic capacitor with silver mica and PTFE dielectric. As this kind of capacitor is widely used in many electronic devices, it is important to understand not only its application field but also its working principle.

Firstly, the application field of the CM04ED390JO3 capacitor mainly involves the areas of consumer electronics and automotive electronics. As an example, it is majorly used in radio frequency (RF) signal applications for high-frequency isolation in portables and cell phone antennas. It can also be used in video, audio, industrial, medical, etc. Secondly, the CM04ED390JO3 capacitor has several advantages due to its mica dielectric. It can provide good efficiency in high frequency applications with low power dissipation. Furthermore, it offers extended stability in various thermal circumstances, meaning that its capacitance and dissipation factor values have good linearity for a wide range of temperature variation. Finally, its excellent voltage endurance ability makes it suitable for circuits subjected to high surge voltages.

Now we have a better understanding of what the application field of the CM04ED390JO3 capacitor is. But to deepen our knowledge, let’s move on to the working principle of this capacitor. This mica capacitor is mainly made of silver-mica dielectric and PTFE insulation. Silver mica works as a dielectric in the capacitor structure, while PTFE adds insulation and provides a reliable method for adsorption of the mica capacitor to the pin. The CM04ED390JO3 capacitor works on the same principle as all other mica capacitors. That is, the silver mica between each layer functions as a medium for storing electrical charges. These charges are further managed by the PTFE layer, which regulates the capacitance value. As a result, the capacitor can offer high capacitance values, high frequency responses, and good temperature stability.

It is clear that the CM04ED390JO3 capacitor is a well-rounded component with an efficient application field and working principle. Its use in consumer electronics and automotive electronics has proven to be successful. This ability to be used in various industries is due to its advantageous features, such as its superior voltage endurance, extended temperature stability, and high frequency response. With an understanding of the application field and working principle of the CM04ED390JO3 capacitor, it is obvious why this capacitor stands out as a quality capacitor among others.
