Mica and PTFE capacitors are electroceramic capacitors composed of mica and PTFE (Teflon). They are commonly used in high frequency circuit applications due to their excellent high temperature and high frequency characteristics. The CDV30FH271GO3 is an example of a mica and PTFE capacitor from TDK.

Application Field

The CDV30FH271GO3 mica and PTFE capacitor have a wide range of applications, especially among high-frequency circuits. Some of its common uses include timing devices, filters, and oscillators. In these types of circuits, the capacitor is used to store energy and enable high speed signal transmission. Thanks to its excellent temperature and frequency characteristics, it also has many aerospace and defense applications.

Working Principle

The working principle of the CDV30FH271GO3 mica and PTFE capacitor is based on the process known as dielectric charging. When a voltage is applied between two conducting plates, the electric field generated between them produces a corresponding electric flux. This electric flux causes a buildup of electric charges on the surface of the dielectric material – in this case, the mica and PTFE – forming a charge separation even when the voltage is removed.

This charge separation creates an electric field which further increases the dielectric constant of the material and consequently provides improved capacitance. This improved capacitance can be used for a variety of applications, such as timing devices, oscillators, and filters.

Thanks to its excellent temperature and frequency characteristics, the CDV30FH271GO3 mica and PTFE capacitor is well-suited for use in high-frequency and high-temperature applications. In such applications, its improved dielectric constant makes it a great choice for storing energy and enabling high-speed signal transmission.
