Mica and PTFE capacitors are an important subclass of ceramic capacitors and have a number of distinct properties and advantages that make them highly desirable in many different applications. The CMR04E620JPDM capacitor is one such device that makes use of mica and PTFE technology to provide excellent performance. This article examines the application field of the CMR04E620JPDM as well as its working principle.

The CMR04E620JPDM capacitor is a high-capacitance, low-loss rated device with an operating voltage of 2.5V. It is designed for use in high-frequency switch-mode power supplies, motor controllers, and other applications that require a capacitance of more than 100nF and extremely low losses. Its ceramic dielectric is made from mica and PTFE, and its combination of low inductance, high capacitance, and very low leakage current give it an exceptionally low equivalent series resistance (ESR).

The use of mica and PTFE technology helps to ensure that the CMR04E620JPDM capacitor has a high level of efficiency, even in high-frequency applications. The dielectric is made from a blend of mica and PTFE, which makes it remarkably stable in terms of capacitance and dissipation factor, and gives it excellent power-handling capabilities. Additionally, the dielectric offers a very low dielectric absorption rate, which helps to ensure a longer life span and reduce its audible noise emission. It also has a high breaking-voltage rating of over 1 kV.

The working principle of the CMR04E620JPDM capacitor is based on the use of two ceramic layers that are interwoven between two metal electrodes. The ceramic layers are made from mica and PTFE and, when placed between the two electrodes, form a dielectric material that can store charge. This stored charge creates an electric field that opposes the applied voltage to create a capacitance. As the electric field increases, so does the capacitance of the capacitor, allowing it to store more charge. When the applied voltage is removed, the charge stored in the capacitor discharges as electric current. This allows the capacitor to act as a condenser, and the magnitude of the current passing through it follow the principles of Ohm’s Law.

The CMR04E620JPDM capacitor is most often employed in power supply and power converter applications, such as motor controllers and power supplies for electronic circuits. Its design makes it ideal for use in low-loss and highly-reliable power converters and switch-mode power supplies, as the high capacitance allows for efficient power storage and the low-loss design reduces audible noise. Additionally, its low inductance design allows it to operate at high frequencies without compromising its performance. It can also be used in applications that require the same level of performance but lower capacitance values.

In conclusion, the CMR04E620JPDM capacitor is an excellent choice when it comes to mica and PTFE capacitor technology. It is designed for use in high-frequency, high-efficiency, low-loss and reliable power solutions, including motor controllers, power supplies, and other applications that require high capacitance values without sacrificing performance. Its combination of excellent stability, high capacitance, and low loss makes it optimal for a wide range of applications.
