Mica and PTFE Capacitors

Mica and PTFE (Polytetrafluoroethylene) capacitors are types of capacitors which use mica, a natural non-metallic mineral, or PTFE, a synthetic polymer, as their dielectric material. They are also referred to as film capacitors due to their construction. Mica and PTFE capacitors are used in a variety of applications from low- and high-frequency circuits to medical electronics, RF applications, power supplies, and automotive electronics.

CDV30EF390GO3F Application Field and Working Principle

The CDV30EF390GO3F is a mica and PTFE capacitor that is widely used in a variety of electronic applications. It is a surface mount, axial-lead capacitor that features low ESR, high ripple current capability and excellent frequency response. The capacitor offers standard capacitance values ranging from 1μF to 10μF.

The CDV30EF390GO3F works in an analogous way to any other capacitor where two charged plates of opposite polarity create an electrical field between them. This electrical field is an effective barrier to current, which is how it works as a capacitor. However, the dielectric material used in mica and PTFE capacitors allows for higher levels of current compared to other types of capacitors.

The key advantages of using mica and PTFE capacitors are their excellent capacitance stability and low temperature coefficient. They also feature high working voltages and low losses (low ESR), making them an ideal choice for power supplies and power supply filters. The CDV30EF390GO3F has a rated working voltage of 30VDC, a 0.06µF capacitance, and a 0.95µF ESR. With its low current leakage and its ability to operate in temperatures up to 85°C, the CDV30EF390GO3F is well-suited for a variety of uses, including motor drives, automotive electronics, and audio equipment.

Conclusion

The CDV30EF390GO3F mica and PTFE capacitor offers a low ESR, high ripple current capability, and excellent frequency response. With its low current leakage, high working voltage, and high capacitance stability, the CDV30EF390GO3F is ideal for uses such as motor drives, automotive electronics, and audio equipment.
