Mica and PTFE capacitors are widely used for capacitive applications in electronic circuits. Their compact size, low cost, and durability make them an attractive option for many applications. One particular type of mica and PTFE capacitor, the CMR05E680JPDP, has proven itself particularly useful due to its robustness, high capacitance, and low equivalent series resistance. This article will discuss the application field and working principle of the CMR05E680JPDP.

Application Field

Most capacitors are primarily used to filter out AC voltage and store electrical energy. However, this particular capacitor stands out due to its ability to handle high voltage and currents efficiently. The CMR05E680JPDP is primarily used in high-end aerospace and military applications, primarily due to its high voltage rating (up to 6.8kV). Its low equivalent series resistance makes it an excellent choice for energy storage applications, such as boost converters and inverters.

The CMR05E680JPDP is also popular for HVDC transmission lines due to its high capacitance and robust construction. Its low equivalent series resistance helps reduce transmission losses when transmitting power over long distances. Additionally, its robust construction makes it an excellent choice for harsh environmental applications.

The CMR05E680JPDP is also widely used in automotive applications, mainly due to its low equivalent series resistance and voltage rating. It is an excellent choice for automotive power supplies, especially when used in combination with a dielectric oil. The CMR05E680JPDP is also often used in automotive electric motors and alternators, where its robust construction and high capacitance are invaluable.

Working Principle

The CMR05E680JPDP is a type of mica and PTFE capacitor. It is composed of two mica electrodes which are coated with polytetrafluoroethylene (PTFE). The mica plates are separated by a thin layer of air which creates an effective dielectric that allows the capacitor to store large amounts of electrical energy. When a voltage is applied across the plates, the mica plates become charged and are able to store a significant amount of electrical energy.

The CMR05E680JPDP is often referred to as a “non-electrolytic” capacitor due to its unique design. Unlike electrolytic capacitors, mica and PTFE capacitors are not dependent on electrolytes for their operation. This makes them ideal for applications where reliability and durability are of the utmost importance. Additionally, this type of capacitor has a very low equivalent series resistance, which allows it to handle high voltages and currents efficiently.

In summary, the CMR05E680JPDP is an invaluable capacitor for many applications due to its high voltage rating, high capacitance, low equivalent series resistance, and robust construction. Its wide range of applications, from automotive power supplies to HVDC energy transmission lines, make it one of the most versatile capacitors available. It is an excellent choice for any electronic circuit where reliability and durability are key considerations.
