Mica and PTFE Capacitors
Mica and PTFE capacitors are two of the most commonly used type and materials of capacitors. Mica capacitors, also known as mica disc capacitors, are made using mica as an insulating material and are usually constructed from two thin or thick mica plates dielectric, with a metallic film on either side. The films can be either aluminum or silver. The mica material’s high thermal stability and extremely low dielectric loss coupled with the metal film’s better electrical conductivity result in extremely reliable capacitors. Mica capacitors are most often used in high-frequency applications, including radio transmitters and receivers.
A PTFE (Polytetrafluoroethylene) capacitor is a type of capacitor made with thin sheets of material made from a polymer consisting of Carbon, Fluorine, and Oxygen atoms. It is also known as Teflon. This material’s outstanding dielectric properties and extremely low dielectric loss make it suitable for use in a wide range of capacitors. PTFE capacitors are used in high-frequency applications, such as RFid and audio equipment, and in low-frequency applications, such as filters, where space is limited and weight is a concern. PTFE capacitors can also be used in high voltage (HV) applications, and are the preferred choice for these types of applications due to their low mechanical and thermal stress stability.
CMR06F821JODR is is one type of PTFE capacitor. This capacitor has a high dielectric constant and a capacitance tolerance rating of ± 2% to 4%. It has a working voltage of 20KV DC and an insulation resistance of > 10100 Ohm. The capacitance is 1pF to 1500pF. The maximum operating temperature is 85°C and the capacitance temperature drift is ± 2%/°C. The CMR06F821JODR is designed for use in RF communication applications, such as FM radio transmitters and receivers, VHF and UHF handheld radios, and cellular phones. The capacitor is also suitable for use in filtering, switching, and voltage regulation applications.
The CMR06F821JODR capacitor has a working principle based on the principle of electrostatic capacitance. Its operation is based on the use of two conductive plates, which are separated by an insulating dielectric material. The insulating dielectric material can be PTFE, mica, or ceramic. When a voltage is applied to the capacitor, an electric field is set up between the two plates and they are charged with opposite polarity. The plates act like two spheres in a capacitor, allowing them to hold an electric charge and store energy. The electric field acts like a barrier that blocks the flow of current. This is how capacitors store and release electrical energy.
In summary, the CMR06F821JODR capacitor is one type of PTFE capacitor, which is made of PTFE material and is ideal for high frequency applications such as RF communication. Its unique working principle is based on the principle of electrostatic capacitance, and it is designed to store and release electrical energy. This capacitor offers a high dielectric constant and a capacitance tolerance of ± 2% to 4%, making it a reliable option for a variety of applications.
