Mica and PTFE capacitors are one of the most common types of capacitors used in many high-frequency, high-current, and ultra-precise applications. Some examples include high-speed data detection, broadband radio frequency systems, signal processing, and telecommunications. The CDV30FH752FO3F is a mica and PTFE-based capacitor suitable for many of these applications, thanks to its unique properties. This article will discuss the application field and working principle of this capacitor.

Application Field: The CDV30FH752FO3F is a stable, high-frequency, general-purpose mica and PTFE capacitor. It is able to operate effectively at temperatures ranging from -55°C to +105°C, which makes it an ideal choice for temperature-sensitive, high-frequency applications. Its high Q-factor and stable operating voltage capabilities make it an ideal choice for high-precision, high-frequency circuits such as those used in radio frequency systems, broadband systems, and signal processing. It is also suitable for direct current blocking and DC-DC power supplies.

Working principle: The mica and PTFE capacitors are parasitic capacitors formed by using a thin dielectric layer between two metallic conductors. The dielectric layer is formed by an insulating material such as mica, making this capacitor unique in its ability to operate effectively at very high frequencies thanks to its low electrical losses. The structure of the capacitor is further enhanced by the addition of another dielectric layer, such as PTFE, which increases the capacitance and improves the reliability of the capacitor. The two layers also reduce the effect of the inner conductor on the behavior of the outer conductor.

The CDV30FH752FO3F is able to handle up to 6A at frequencies ranging from 1kHz up to several GHz. Its self-resonant frequency is around 25MHz, allowing it to be effectively used in high-precision applications where signal integrity is crucial. Since it is a low-DC resistance capacitor, it is also suitable for many DC blocking and DC-DC power supply applications. Its operating temperature range and small size make it a suitable choice for temperature-sensitive and high-frequency applications in telecommunications, signal processing, and broadband systems.

The CDV30FH752FO3F is a high-precision, temperature-stable, high-frequency mica and PTFE-based capacitor. Thanks to its stability, reliability, and small size, it is suitable for many of the small, high-precision applications where signal integrity and low-DC resistance is required. It is also ideal for direct current blocking and DC-DC power supply applications, as well as for high temperature applications due to its relatively wide operating temperature range. It is the perfect solution for many high-frequency applications.
