Mica and PTFE Capacitors

MCH38FK271J is a kind of mica and PTFE capacitors, the model number has specific meanings. “MCH” refers to the type code, showing that it is a kind of mica and PTFE capacitors. The following two characters means the capacitance tolerance, “38” refer to it +/-10%. The following two characters indicates type of termination, “FK” refer to end leads tin-plated solder-dipped. The last five characters shows the capacitance value, “271J” refer to 2700pF.

Mica and PTFE capacitors are widely used in a variety of electrical components, including DC blocking, bypass, power factor correction as well as signal and frequency filters. Mica and PTFE capacitors are attractive candidates for RF tuning and other high capacitance applications because of their high safety and performance, low power loss, low dissipation factor and frequency/temperature stability. The combination of mica and PTFE, when used as the dielectric, provides superior performance compared to standard plastic capacitors in high-powered applications, such as switch-mode power supplies and other high-voltage power supplies.

The working principle of mica and PTFE capacitors is that it has two conductors which are separated by a dielectric material. When it is exposed to a voltage, electrons distribute, they expose the inner surface of the conductor to the electron field, forming an electric field. This electric field then causes an electric current to flow between the two conductors. This current produces a voltage drop across the capacitor, which is exactly equal to the applied voltage. The voltage drops increase with increasing conductivity of the dielectric, capacitance value and frequency of the applied voltage.

Mica and PTFE capacitors are increasingly used in high temperature applications because of its excellent energy efficiency. It has low power loss and low dissipation factor, which mean it can dissipate heat effectively, preventing the system from overheating. The combination of mica and PTFE materials improves the service life and frequency stability, making them suitable for a wide range of applications from audio equipment to medical devices. Moreover, it has good self-healing capabilities in the event of a short circuit, so it is suitable for applications where safety is a priority.

In conclusion, MCH38FK271J is a mica and PTFE capacitor with high safety and performance, low power loss, low dissipation factor and temperature stability, and it is suitable for a wide range of applications. Its working principle is based on the formation of an electric field which causes a current to flow between the two conductors, and its excellent energy efficiency makes it suitable for use in high temperature applications.
