Mica and PTFE capacitors are widely used for a variety of applications in modern electronic and electrical technologies requiring high electrical performance, stability and reliability. Of these, CD5CC090DO3F is an ultralow ESR mica capacitor specifically designed for extremely low impedance applications and provides excellent electrical characteristics such as low ESR (equivalent series resistance), high stability and high reliability.

Mica and PTFE capacitors, such as the CD5CC090DO3F, are primarily used in high-frequency circuits such as switching power supplies, high-end audio systems and so forth. This capacitor can also be used in low power applications, such as RF receivers, transmitters and high gain amplifiers, where conventional capacitors do not meet the required performance levels.

The construction of the CD5CC090DO3F capacitor comprises a ceramic dielectric surrounded by metalized mica. The metalized mica, encapsulated in PTFE , enhances the capacitance and reliability of the mica capacitor, while at the same time providing a high degree of mechanical, electrical and thermal stability. This balance of properties allows for a wide range of applications in both high-frequency and low-power electronics.

The electrical behavior of the CD5CC090DO3F capacitor is governed by the working principle of electrostatic capacitance. This working principle states that at any given voltage, an electric field is produced between two conductors separating them. This field then attracts electric charges of like sign, thus creating a stored energy state between two conductors known as capacitance. This means that the capacitor can store energy while an electric current is flowing through it, and then discharge the energy when the current is reversed.

In the CD5CC090DO3F capacitor, the distance between the two conductors (made of either silver or gold) is minimized, resulting in the opportunity to store a higher amount of energy. The capacitor’s ceramic dielectric further helps to decrease the amount of energy lost during the charge/discharge process. This combination of mica and PTFE capacitors helps to obtain the desired electrical parameters and increase the reliability and stability of the capacitors.

In conclusion, the CD5CC090DO3F mica and PTFE capacitor is designed for high-frequency applications as well as for low power ones, providing excellent electrical characteristics such as low ESR, high stability, and high reliability. Its working principle is based on electrostatic capacitance, which enables it to store and discharge electrical energy with minimal losses.
