Mica and PTFE Capacitors: CDV30FH752JO3F application field and working principle

Mica and PTFE capacitors meet the needs of numerous applications ranging from power electronics, aerospace, industrial, automotive, medical, and even communications. The capacitance in mica and PTFE capacitors relies on the influence of two variables, namely the mica size and the thickness of the PTFE layer. An overview of the application field and working principle of the CDV30FH752JO3F capacitor is provided in this paper.

Application Field

The CDV30FH752JO3F capacitor has a wide range of applications. A few of the most popular are as follows: It is used as part of an electronic power system, such as a power factor correction system, due to its high volumetric efficiency and excellent temperature stability. Additionally, it is used for filtering ripple in automotive circuits, due to its high dV/dt capability and low ESR/ESL. Furthermore, it is used in medical and laboratory equipment because of its small size and dielectric properties. Lastly, in the field of telecommunications, the CDV30FH752JO3F is utilized in cell phones, satellite communications, and high-frequency applications.

Working Principle

The CDV30FH752JO3F capacitor works based on a static electric field. The static electric field between the two conductive plates is modulated by the dielectric material, which is composed of a laminate of mica and PTFE. As the voltage across the two plates is increased, an electric field is formed between them. The electric field acts to maintain the displacement of the dielectric material, and as a consequence, the effective capacitance is increased.

When the voltage is removed, the electric field is eliminated and the displacement between the plates is reduced, resulting in a decrease in capacitance. This principle is used to allow capacitors to store a voltage over a period of time. Additionally, the mica and PTFE combination acting as a dielectric material provides the CDV30FH752JO3F with excellent temperature stability, excellent environmental resistance, and high insulation resistance.

Conclusion

In conclusion, the CDV30FH752JO3F is a mica and PTFE capacitor with a wide range of applications in power electronics, aerospace, industrial, automotive, medical, and telecommunications. Its working principle is based on the static electric field formed between two conductive plates, which is modulated by the mica/PTFE dielectric material. This combination provides the capacitor with excellent temperature stability, excellent environmental resistance, and high insulation resistance.
