Mica and PTFE capacitors are widely used in many modern day applications from wireless communication devices to satellite communication and even automotive technology. The CD7FA621GO3 is one such capacitor that is designed using a combination of mica and polytetrafluoroethylene (PTFE) dielectric material. It is a small and lightweight capacitor with low ESR and high capacitance values.

The CD7FA621GO3 is a polarized capacitor and can provide a wide range of capacitance values ranging from 10pF to 560pF. The dielectric constant and dissipation factor are comparatively high at 600V at a maximum temperature of 125C. The dielectric strength of the dielectric material used in this capacitor is 450V and it has a low dielectric absorption ratio of 4.

The CD7FA621GO3 has a wide range of applications ranging from high frequency power supply applications to RF signal applications. It is especially suitable for use in power converters and high frequency switching regulators. The CD7FA621GO3 is very stable and reliable and provides protection against overvoltage in power supplies. It is also used as a DC blocking capacitor in RF signal applications to block the signal from passing through the power supply rail while allowing the AC components to pass through.

The capacitor works by storing electrical energy in its dielectric when a voltage is applied across its terminals. The energy is then slowly released as the voltage across the terminals drops. The energy stored in the dielectric is directly proportional to the capacitance of the capacitor and is inversely proportional to the dielectric constant which is a measure of the energy loss per unit volume of the dielectric material. The total capacitance of the capacitor is determined by the total volume of the dielectric material in the capacitor.

Mica and PTFE capacitors such as the CD7FA621GO3 are very popular for use in many high-frequency applications because they provide excellent dielectric characteristics, stability, and reliability. They offer an excellent high frequency performance and are very economical compared to other capacitor types.

The CD7FA621GO3 is also highly compatible with RoHS compliant parts, making it even more attractive for use in a wide range of applications. It is also one of the few capacitors that can be used in extreme temperatures and in high humidity environments without any issues. As a result, it is often seen as the preferred option for use in a variety of applications.
