Mica and PTFE Capacitors: MC12CD090C-F Application Field and Working Principle

Mica and PTFE capacitors are widely used in a variety of applications and are some of the most efficient capacitors available. The MC12CD090C-F is one such capacitors, and it carries with it a high level of performance and durability.

What is a Mica and PTFE Capacitor?

The MC12CD090C-F is a double-ended mica and PTFE capacitor, or capacitor constructed of a mica dielectric and PTFE film for insulation. This type of capacitor is popular for its excellent performance in high-frequency applications, compared with other types of capacitors. The mica dielectric is constructed in two layers and is capable of withstanding extremely high temperatures. Its excellent temperature capability and its excellent maximum operating temperature of 125° Celsius, make it highly suitable for use in high-performance and high-temperature power supply applications. The capacitor\'s robust nature and high current capability makes it ideal for such applications. The PTFE insulation film is extremely flexible, and when combined with the mica dielectric, offers an excellent level of dielectric strength which enables the capacitor to withstand high voltage applications and protect against short circuits or dielectric breakdown over time.

Applications and Features

The MC12CD090C-F capacitor is ideal for use in power supplies, switched mode power supplies, audio frequency amplifiers, motor starters, electronic switching circuits, IGBT modules and other high-frequency applications.The MC12CD090C-F is constructed with a sturdy, stainless steel case, which makes it highly durable and capable of withstanding extreme environmental conditions. It also has a low equivalent series resistance and high ripple current rating, making it suitable for use in high-frequency DC/DC converters and high-current switched power supplies. Additionally, the capacitor is RoHS compliant, making it suitable for use in a wide variety of applications.

Working Principle

Mica and PTFE capacitors work by utilizing the reverse bias dielectric strength of the mica dielectric. The dielectric strength of the mica dielectric helps protect against short circuits and dielectric breakdown over time, as well as providing a high level of capacitance retention over time.The PTFE insulation film also aids in increasing capacitance retention over time by limiting the amount of leakage current which can flow through the capacitor. As the capacitor ages, the level of insulation film increases, which helps prevent dielectric breakdown due to aging. Additionally, the flexibility of the PTFE film helps reduce distortion at high frequencies, making the capacitor ideal for use in high-frequency applications.

Conclusion

The MC12CD090C-F is an excellent choice for a number of high-performance applications as it offers robust performance and excellent temperature and ripple current ratings. Its flexible, insulating PTFE film helps it withstand high frequencies and offer good capacitance retention over time. Additionally, its RoHS compliant status makes it suitable for a wide range of applications.
