Mica and polytetrafluoroethylene (PTFE) capacitors, such as the CD19FC622FO3, are kinds of ceramic capacitors. Mica and PTFE capacitors are superior to other types of dielectric capacitors because of their very low dielectric losses, excellent stability, and their wide temperature range. They are used in a variety of industries, from aerospace to automotive electronics.

The CD19FC622FO3 capacitor is a surface-mount device that is designed to provide high levels of stability and reliability. It features an internal construction of two capacitors with polytetrafluoroethylene (PTFE) dielectric and gold-plated endplates. The capacitor has an operating temperature range of –55^oC to +105^oC.

Application Field

The CD19FC622FO3 and other mica and PTFE capacitors are used for a variety of applications, including high-frequency filtering, RF power amplifiers, and voltage stabilization. They are also commonly used in medical devices, automotive electronics, and industrial automation applications. Additionally, they are used in television power supplies and in communications equipment.

Mica and PTFE capacitors are also used in electrostatic discharge (ESD) protection circuits, such as are used to protect sensitive components from damage due to static electricity. They are used to provide additional resistance to electrostatic and electric fields, while providing increased stability, temperature resistance, and vibration-resistance than other types of dielectric capacitors.

Working Principle

The working principle of the CD19FC622FO3 and other mica and PTFE capacitors is based on its internal construction of two capacitors with polytetrafluoroethylene (PTFE) dielectric and gold-plated endplates. The two capacitors are connected in series, with the polytetrafluoroethylene (PTFE) dielectric acting as an isolator between the two capacitors. This isolator helps reduce the amount of leakage current, while also preventing any short-circuiting between the two capacitors.

When power is applied to the capacitor, the two capacitors charge in opposite directions, causing an electric potential to build up across the PTFE dielectric. This electric potential creates an electric field, which is stored in the form of an electric charge. The capacitor then discharges this stored charge in the form of an electric current when the power is removed. The Polytetrafluoroehtylene (PTFE) dielectric helps to reduce the amount of charge leakage, providing a high level of stability and reliability.

Mica and PTFE capacitors are widely used due to their reliability, low dielectric losses, and wide temperature range. They provide excellent filtering capabilities for high frequency circuits, accurate voltage stabilization, and protection from electrostatic discharge. Furthermore, they offer good vibration resistance and are suitable for high temperature environments.
