Mica and PTFE Capacitors

Mica and PTFE capacitors are used in many different electronics and engineering applications due to their reliability, low loss, and wide operating temperature range. The MC22FA112J-TF is one of the latest capacitors with improved features and technology, providing excellent performance and reliability in its field of application.

Application Field

The MC22FA112J-TF mica and PTFE capacitor is primarily used in high power applications, particularly in high output rectifiers or amplifiers. The capacitor combines mica and PTFE dielectric materials to form an extremely safe and reliable device, with a maximum rated voltage of 1000V. This capacitor has superior temperature characteristics and is designed to withstand frequencies up to 10MHz.

The MC22FA112J-TF capacitor is highly heat resistant, having a thermal resistance of 0.005 degrees Celsius per watt, and hence is suitable for use in areas of extreme temperatures. It is also highly resistant to volt aging, with an average voltage coefficient of less than 0.01% per decade. This makes it suitable for long-term use in high-voltage applications.

In addition, this capacitor is highly efficient with an internal series resistance of 0.04 mΩ and a maximum capacitance of 2200 μF. This makes it ideal for use in applications where power efficiency is essential for optimal performance.

Working Principle

The MC22FA112J-TF capacitor works based on the principle of electrolytic capacitance. Electrolytic capacitors are made up of two different types of electrodes that are separated by an electrolyte. The two electrodes are made of an insulating material called a dielectric and it is this that provides the capacitor\'s ability to hold electrical charge.

When electrical energy is applied to one of the electrodes, a voltage is created that causes a flow of electrons from the positive electrode to the negative electrode. This flow of electrons is then stored in the capacitor\'s electric field. When the electrical current is removed, the electrons remain stored in the electric field, ready to be released again when a new voltage is applied.

The MC22FA112J-TF capacitor is constructed using a combination of mica and PTFE dielectric materials. Mica is an insoluble mineral and it has very low dielectric losses while PTFE, also known as polytetrafluoroethylene, is an extremely stable high dielectric material. This combination provides excellent thermal stability and high dielectric strength, allowing the capacitor to be safely used in harsh environments and at high voltages.

The MC22FA112J-TF capacitor is a reliable choice for many different electronics and engineering applications. Its combination of reliable performance, low loss, and wide operating temperature range make it suitable for high power and wide temperature applications.
