Mica and PTFE capacitors, such as CD42FD223GO3F, are larger and less commonly used than ceramic or electrolytic varieties.They are formed by combining sheets of metal foil with dielectric layers, which may be mica, polyamides, and/or PTFE, among others. Due to their higher conductivity and breakdown voltage, and small size, they are most often used as high frequency capacitors, designed for applications requiring stability over a wide range of temperatures and power levels.

One major feature of mica and PTFE capacitors is their low losses or dielectric absorption. This means that the capacitor can handle a greater charge at higher operating frequencies, making them useful in radio frequency (RF) applications. This also allows them to be used in low power environments, such as those found in digital systems.

CD42FD223GO3F capacitors, specifically, are designed for high frequency, high temperature automotive circuits. They have a high dielectric absorption capacity, making them a great choice for applications requiring high accuracy and stability under varying loads. They possess an enhanced capacitance-to-weight ratio that reduces volume and size, as well as mounting time; and a shorter life cycle than other capacitors with similar specifications.

The working principle of these capacitors is as such: one sheet of metal is sandwiched between two layers of dielectric - mica or PTFE - that acts to insulate the two layers of metal from each other, thereby forming a capacitor. As an electric current is applied between the two layers of metal, charges accumulate on the surfaces of each layer, forming an electric field between them. This electric field is capable of storing electrical energy for a short period of time, and this energy can be released when needed.

In conclusion, CD42FD223GO3F capacitors are used in high frequency circuits due to their low losses and smaller size compared to other capacitor varieties. Their high dielectric absorption capacity makes them suitable for use in low power environments, and they possess an enhanced capacitance-to-weight ratio that reduces volume and size, as well as mounting time. Furthermore, the working principle of these capacitors includes an electric field being formed between two layers of metal, which is capable of storing energy for a short period of time.
