Working principle of CD15FD301FO3F capacitors

The CD15FD301FO3F capacitors consist of two sets of metallic films and two mica sheets.In the electric circuit,each mica capacitor is coated with a metallized layer metallic film.And the two layers of metal films are separated and insulated by two sheets of mica,forming one capacitor.The two electrodes are electrically connected,forming a capacitive coupling due to the gap of mica in between.The capacitance of the CD15FD301FO3F capacitor is mainly related to the area of the electrode,the thickness of the mica substrate and the dielectric constant of the mica.The capacitance of the capacitor can be adjusted by changing the size of the electrode.When the associated load is different,the capacitance of the capacitor may change slightly due to the change of the dielectric ratio of the mica.The leakage current of the mica capacitor is mainly related to the quality of the mica sheet and the cathode coating,if the quality of the oxide film is too low,the leakage current will increase greatly,which affects the performance of the capacitor.

Conclusion

In summary,the CD15FD301FO3F capacitor is a type of mica and PTFE capacitor.It has excellent performance in terms of uniformity,frequency response,stability,dielectric strength and leakage current,The application field of the capacitor is very wide,It is widely used in radio reception,electronic equipment and measuring and control circuits.The working principle of CD15FD301FO3F capacitor is mainly determined by the size of its electrodes,the thickness of the mica substrate and the dielectric constant of the mica.
