CDV30FH202GO3F Application Field and Working Principle

Mica and PTFE capacitors have become widely used in both industrial and consumer applications due to their high energy density, ruggedness, stability, and excellent performance in comparison to other types of capacitors. The CDV30FH202GO3F is a mica and PTFE capacitor specifically used in high frequency high temperature applications. This capacitor has a dielectric material of polytetrafluoroethylene (PTFE) with voltage resistance up to 300 high temperature. This type of capacitor generally comes in a 7.5x15 mm snap-in package and is suitable for reflow soldering.

The CDV30FH202GO3F capacitor consists of two thermally bonded silver electrodes on a dielectric core principally composed of PTFE and mica flakes with a metal layer at the bottom and a silver/aluminum metal film on the top. This PTFE-Mica layer provides a high temperature insulation between the input and output terminals of the capacitor and ensures greater tolerance for continuous high temperatures.

The working principle of this mica and PTFE capacitor is straightforward. When voltage is applied to the capacitor\'s terminals, it creates an electric field between the two that attracts the electrons of the dielectric core toward the negative electrode. This same electric field repels the electrons of the positive electrode thus creating an accumulation of negative charges on the dielectric core and positive charges on the negative electrode. This charge separation results in a capacitive effect.

CDV30FH202GO3F mica and PTFE capacitors offer a wide range of applications in electrical and electronic engineering, ranging from power supply circuits to medical device applications. For example, these capacitors can be used in AC power supplies with frequency ranging from 50 Hz to 300 Hz, in choke-input filters, high frequency switching circuits, among other applications.

These capacitors are also ideal for applications handling high temperature and high frequency signals, such as some industrial, telecommunication, and medical equipment, due to their superior temperature ratings and high thermal stability, as well as their ability to provide high levels of surface mount soldering. They also offer excellent non-linearity, noise suppression, and transient response when used in medium to high frequency RF applications.

The CDV30FH202GO3F mica and PTFE capacitor provides a reliable and efficient solution for applications involving high temperature and high frequency signals. It gives the user greater flexibility and enables them to utilize these components in a variety of circuits. This type of capacitor boasts excellent temperature ratings, superior noise suppression, and excellent surface mount soldering.
