Working Principle

Mica and PTFE capacitors are dielectric capacitors. The construction of the capacitor involves a layer of mica acting as a dielectric between two metal electrodes. The mica layer, in combination with the PTFE layer, creates a high dielectric permittivity, which allows the capacitor to store a large amount of charge. This combination offers excellent dielectric characteristics and low losses over a broad range of frequencies.

The two electrodes of the capacitor are connected to an external power source. As an electrical current flows through the capacitor, both electrodes will potentialize. The mica layer between them will create an electrostatic field, resulting in stored electric energy in the form of electrostatic charge. This stored energy is used as the capacitance of the capacitor. Upon discharge of the capacitor, the charge will be released into an external circuit while providing a specified voltage.

The MIN02-002CC090A-TF capacitor has been designed with temperature compensation in mind to maintain its capacitance over a wide temperature range. The capacitor is also designed with a unique anode-cathode ratio of 6:1 to reduce capacitance change with input voltage. This combination of features allows the capacitor to be used in even extreme environments.

Conclusion

The MIN02-002CC090A-TF mica and PTFE capacitor is a reliable and stable component suited for a variety of applications. The combination of mica and PTFE in the capacitor provides excellent dielectric characteristics and low losses over a large frequency range. The thermal and voltage compensation features of the capacitor also make it ideal for use in various industrial and commercial applications.
