Mica and PTFE capacitors are a type of capacitor that have many different uses in applications ranging from radio frequency communication, medical imaging, as well as industrial and commercial uses. CD30FD512GO3 is a type of mica and PTFE capacitor from the TDK-EPCOS range, which is specifically designed for use in high-frequency communication systems. This article will discuss the application field and working principle of the CD30FD512GO3.

Application Field

The CD30FD512GO3 mica and PTFE capacitor has many applications due to its small size and high capacitance. It is ideal for use in high-frequency applications such as radar systems, satellite communication systems, and broadcast transmitters. It is also used in radio receivers, microwave ovens, and wireless LAN systems. In addition, it can be used to filter and suppress interference in industrial and medical equipment.

The capacitance of the CD30FD512GO3 is 512pF (pico-Farad) with a temperature coefficient of -0.2%. The dielectric losses of the capacitor are low, making it a suitable choice for high-frequency applications. The very low self-resonance frequency (SRF) of the device makes it suitable for use in applications involving resonance circuits. Additionally, the device is available in standard and miniature sizes and can be mounted on a printed circuit board (PCB) for further space savings.

Working Principle

Mica and PTFE capacitors work on the same principle as any other type of capacitor. The CD30FD512GO3 consists of two oppositely charged metallic plates enclosed in a dielectric material, such as PTFE or mica, which serves as an insulator. When a voltage is applied across the plates, a charge is stored between them due to electrostatic attraction between opposite charges. This charge is maintained until the capacitor is discharged.

The capacitance of a mica and PTFE capacitor depends on the material used for the dielectric as well as its thickness and the area of the capacitor’s plates. In the case of the CD30FD512GO3, the dielectric material is PTFE, while its capacitance is 512pF. This relatively high value makes the device suitable for applications where high capacitance is required.

The current carrying capacity of the CD30FD512GO3 is also quite impressive, with a rated current of 2.5 A. This makes it suitable for use in applications where a large current needs to be supplied, such as powering motor drives and high-power amplifiers. Furthermore, the device has a wide operating temperature range of -60°C to +125°C, making it suitable for use in a variety of environments.

Conclusion

The CD30FD512GO3 mica and PTFE capacitor is a versatile device with a wide range of uses in fields such as radio frequency communication, medical imaging, and industrial and commercial applications. Its high capacitance and current carrying capacity as well as its wide operating temperature range make it a suitable choice for many high-frequency applications. Finally, its small size and easy mounting on a printed circuit board make it a great choice for use in space-constrained applications.
