Mica and PTFE Capacitors

Mica and PTFE capacitors are a popular choice for many applications needing a reliable, high-performance capacitor. The CMR06F621FODR series capacitors are one of the most widely used and well-respected mica and PTFE capacitors on the market today. With a range of application fields and working principles, these capacitors offer an excellent performance and stability in a wide range of applications.

Applications Fields

Mica and PTFE capacitors are the capacitors of choice for many different applications across industrial, automotive, telecommunications, and telecom/data communications markets. Cable television and satellite broadcasting systems, cellular base stations, lan/RJ45 connections, and 5G networks are just a few of the applications where these capacitors are used.

Mica and PTFE capacitors are highly reliable and reliable in extreme temperature conditions, making them well-suited for applications that require long-term operation with no maintenance and continuous performance in harsh environments. In addition, these capacitors offer a low equivalent series resistance (ESR) for enhanced reliability and performance. This makes them a great choice for applications such as mobile phones, camcorders, and audio/visual systems that require power efficiency for long-term operation.

Working Principle

Mica and PTFE capacitors work in a similar manner to ceramic and electrolytic capacitors. They each have a dielectric material that allows electrical current to flow between two metal plates (called electrodes). The dielectric material used in mica and PTFE capacitors is highly stable and can sustain significant electrical fields without degrading over time.

In mica and PTFE capacitors, the dielectric material is sandwiched between two metal plates (the electrodes). As current passes through the plates, the capacitor will store electrical energy in the form of a charge. When the current is shut off, the capacitor will allow electrons to flow slowly back through the plates and discharge the stored energy.

Mica and PTFE capacitors are highly sought after due to their excellent temperature stability and dielectric strength, as well as their low ESR. These qualities make them ideal for high-voltage and high-frequency applications, as they can store relatively large amounts of electrical charge despite their small size. In addition, the dielectric material used in these capacitors is non-porous, which means that they are less prone to leakage compared to other types of capacitors.
