Mica and PTFE capacitors, such as the CDS15FD111GO3, are designed for audio, low-noise, and high-frequency applications.

A classic capacitor is constructed of two electrodes, usually made of metallic film or foil, separated by a dielectric material. The mica and PTFE capacitors use different dielectric materials and construction to increase their performance over standard metal film/foil type capacitors.

Mica is a naturally occurring mineral with a high electrical insulation rating and low hysteresis. This combination of properties makes it an ideal material choice for capacitor dielectrics. A mica capacitor is constructed of two metal layers separated by mica substrate. An additional metallized layer is added to account for the wrap-around effect of the mica. This construction results in a capacitor with extremely low leakage current and an excellent frequency response.

PTFE, or polytetrafluoroethylene, is a synthetic plastic material with an extremely high dielectric constant, low electrical losses, high thermal stability, and low electrical noise. PTFE capacitors use two metal layers separated by a PTFE insulating layer. This results in a very low parasitic inductance, making it ideal for use in high-frequency applications.

The CDS15FD111GO3 is a mica and PTFE capacitor that incorporates both technologies to provide superior performance in low-noise, high-frequency, and audio applications. Due to its superior characteristics, the CDS15FD111GO3 is particularly suited for use in high-end audio equipment and digital circuitry. Its low inherent capacitance change over time, low electrical losses, and low electrical noise makes it ideal for use in demanding applications.

The working principle of the CDS15FD111GO3 is based upon electro-magnetic induction. When a voltage is applied across the capacitor terminals, electric charge is stored in the capacitor’s dielectric layer. This charge, in turn, produces an electric field that attracts electrons to the dielectric layer, increasing the amount of charge stored. As the voltage across the terminals is increased, more charge is stored in the dielectric layer, increasing the capacitance of the capacitor.

When the voltage is removed, the accumulated charge is slowly discharged. This discharge, or leakage, is a function of the intrinsic capacitance of the device, as well as the dielectric material. The CDS15FD111GO3 is designed to provide superior performance in terms of capacitance, voltage breakdown, and leakage current.

In summary, the CDS15FD111GO3 is a mica and PTFE capacitor designed for audio, low-noise, and high-frequency applications. The combination of mica and PTFE provides superior performance in terms of capacitance, voltage breakdown, and leakage current. The working principle is based upon electro-magnetic induction and is ideal for use in demanding applications.
