Mica and Polytetrafluoroethylene (PTFE) capacitors are becoming increasingly popular in many different types of electronic applications. One such type of capacitor is the MC12FD470G-TF. This device is part of a family of high-performance, mica and PTFE capacitors that feature an ultra-small form factor, due to their construction of thin layers of mica dielectric and ultra-fine PTFE electrodes. Let us take a look at the application field and working principle of the MC12FD470G-TF.

Application Field

The MC12FD470G-TF is suited for a wide variety of high-frequency circuit applications, primarily where low leakage, low dissipation factor, and high breakdown voltage are required. It is widely used as a bypass capacitor, EMI/RFI filter, and in application of different types of amplifiers, power supplies, coupled resonators, and other RF circuits. This mica and PTFE capacitor is also suitable for applications in high-power industrial control systems, such as lighting circuits, motor control circuits, and similar high-voltage/high-current operations. Additionally, its small form factor makes it well suited for use in pulse-type circuits that require high-speed signal switching.

Working Principle

The core of the MC12FD470G-TF is comprised of special mica and PTFE layer, which are dielectric forms of insulation. Mica is a naturally occurring mineral with a dielectric constant of 8 to 10, while PTFE has a dielectric constant of approximately 2.5. As the capacitor is charged, electric charges build up on the capacitor’s plates. The total amount of charge is equal to the sum of the charges on the two plates. The capacitor acts as a barrier preventing the flow of electric current, which causes a voltage drop across the capacitor. As the capacitor is discharged, the amount of charge decreases until the voltage across the capacitor becomes zero. The MC12FD470G-TF’s special mica and PTFE construction allows it to operate at high frequencies, with excellent insulation stability and minimal losses.

Conclusion

The MC12FD470G-TF is an ideal solution for a variety of applications requiring high frequency circuits. It utilizes high-performance mica and PTFE construction to provide excellent insulation stability and minimal losses. It has been designed for use in high-power industrial control systems, coupled resonators, and other RF circuits, as well as a variety of other high-frequency circuit applications.
