MCM01-001DD470J-F

Mica and PTFE Capacitors

Mica and PTFE Capacitors are a type of capacitor that is constructed using a combination of mica and polytetrafluoroethylene, otherwise known as PTFE. This combination of materials results in a capacitor that has a superior dielectric strength, excellent stability, and superior temperature characteristics than other types of capacitors.

The MCM01-001DD470J-F is a type of mica and PTFE capacitor. It is an axial-leaded, stackable capacitor with a maximum capacitance of .47µF and a rated voltage of 250V. These types of capacitors are typically used for general filtering and coupling where a stable of small value of capacitance is required.

The construction of the MCM01-001DD470J-F is made up of two layers of mica and PTFE. The mica acts as the dielectric material and the PTFE acts as the encasing material for the mica. The two layers are then stacked and held in place by an aluminum can. The aluminum can serves two purposes; it helps to ensure the integrity of the two mica layers and it helps to lower the electrical resistance of the capacitor.

The working principle behind a mica and PTFE capacitor is quite simple; it utilizes the combination of the two materials to provide a steady capacitance when exposed to a voltage. When a voltage is applied to the capacitor, electrons will begin to move through the dielectric material, resulting in a current of electric charge that is stored in the two layers of mica. This stored current of charge acts as a reservoir for the capacitor, and due to the mica and PTFE combination, this stored current remains steady when exposed to various temperatures and frequencies.

Due to the combination of materials used in the construction of a mica and PTFE capacitor, these capacitors are ideal for high-pulse rate or high temperature applications. The combination of mica and PTFE offers excellent dielectric strength, stability, and temperature characteristics which make them well-suited for use in automotive, industrial, and commercial applications.

In conclusion, the MCM01-001DD470J-F is an axial-leaded, stackable mica and PTFE capacitor that is capable of withstanding high temperature and pulse rates. With a maximum capacitance of .47µF and a rated voltage of 250V, this type of capacitor is typically used for general filtering and coupling applications. The combination of mica and PTFE provides this capacitor with excellent dielectric strength, stability, and temperature specifications, making it well-suited for use in automotive, industrial, and commercial applications.
