Mica and PTFE Capacitors

Capacitors are electronic components that store electrical energy in an electrostatic field and eventually release it, typically used in different types of electrical circuits. Mica and PTFE capacitors are employed for various applications in a wide range of industries, like automotive, medical, audio, telecommunication and aerospace. Together with other types of capacitors, like electrolytic capacitors, they can upgrade conventional electrical systems, enhance performance and improve image quality.

One such device is the MC22FA202G-TF, a low profile, quick recovery of 220nF ceramic mica and PTFE capacitor designed specifically for critical SMT applications. This component is highly reliable and suitable for extended operation at temperatures up to 125°C. It is packaged in a low cost SIP (Single In-Line Package) format and widely used in high speed digital and analog circuits as well as power systems.

Application Field

The application field of the MC22FA202G-TF capacitor can be divided mainly into three categories: automotive, medical and computer systems.

• In the automotive sector, the MC22FA202G-TF capacitor is used in speed sensors, power supply lines, ECU circuits, radio receivers and many more.
• In the medical sector, the MC22FA202G-TF capacitor can be used in ECG circuits, power supply boards and ultrasound machines.
• In computer systems, the MC22FA202G-TF capacitor is used for power supply, image enhancement processors, voltage regulation circuits, and CPU system boards.

Moreover, the MC22FA202G-TF capacitor can also be used in applications for telecommunications, space and military installations, consumer products, and electrical power networks.

Working Principle

Mica and PTFE capacitors work on an electrostatic principle. When two electrically conducting plates are suspended in an electrical field, the electric charge is shared between them, creating an electrical field that appears as capacitance. In the MC22FA202G-TF capacitor, the two plates are actually two sheets of mica and PTFE material, which are suspended between a special ceramic dielectric. The ceramic dielectric allows for low voltage and high volumetric efficiency, resulting in greater performance in even the toughest of environments.

This capacitor is also designed to operate at high temperatures up to 125°C and it features a quick recovery time, so that any transient voltages can be effectively absorbed, preventing breakdowns in the circuit. This also helps to extend the life of the device and reduce the risk of permanent damage.

Mica and PTFE capacitors are an extremely versatile type of device and the MC22FA202G-TF is an excellent example. It is capable of providing reliable performance in a variety of applications, thanks to its low profile design, high temperature operating capability and quick recovery of time.
