CDV30EF270FO3

Mica and PTFE Capacitors

Mica and PTFE capacitors have a wide range of applications, from processing and filtering signals in telecommunications and networking systems to measuring and calibrating instrumentation. They can also be found in many consumer and industrial applications, ranging from radios and digital televisions to medical equipment and power supplies.

The CDV30EF270FO3 capacitor is a surface mounted lead type mica/PTFE capacitor Kit that is designed for RF and other high frequency applications. It is one of the most common capacitors used in these applications due to its low ESR, high frequency bandwidth and high self-healing capabilities.

Application Field

The CDV30EF270FO3 can be used in a variety of high frequency applications, such as RF amplifiers, filters, attenuators, oscillators, RF mixing and signal conditioning. It is commonly used in radio receivers, TV transmitters, broadband networks and high frequency medical devices where speed and a low level of signal distortion are desired.

Working Principle

Mica/PTFE capacitors are composed of a dielectric material (PTFE) coated with a thin mica sheet and metalized films. The metallic film acts as the top and bottom electrodes. The mica dielectric layer acts as a guard against mechanical stress and offers an additional layer of protection against moisture, chemicals and impacts.

The construction process starts with a mica sheet, which is then treated with a solution containing a conducting polymer. The so-called “metallized films” are then deposited on both faces of the mica sheet before finally being attached to the electrodes. The metal film on the top and bottom electrodes determines the capacitance value of the unit.

The CDV30EF270FO3 is designed with a high performance mica/PTFE dielectric combination which results in excellent capacitance, low ESR (Equivalent Series Resistance), low cost, and a high voltage rating. It is also highly reliable, being resistant to corrosion, mechanical stress, high temperatures, vibration, and shocks.

Conclusion

The CDV30EF270FO3 is a surface mounted lead type mica/PTFE capacitor Kit that is highly dependable and capable of withstanding extreme environments. It is often used in a variety of high frequency applications such as RF amplifiers, filters, attenuators, oscillators, RF mixing and signal conditioning. Its wide range of applications, reliability and durability make it a great choice for any application requiring the highest performance.
