Mica and PTFE CapacitorsMica and PTFE capacitors have been in use for several decades and are used in a variety of applications. They are widely used in high-frequency electrical components, in both radio and television, in communications systems, computer equipment, and in various aerospace and military locations.Mica capacitors are composed of two plates of metal with a dielectric property of mica, which is a natural mineral and is able to store energy as an electrical field. The two plates inside the capacitor are either made of copper or aluminum and are insulated by mica. This provides a wide range of electrical characteristics for the capacitor. The metal plates are kept in place by a mica sheet, which has a central hole in it for the contact terminals.PTFE capacitors are similar in design, but the dielectric is a synthetic fluorocarbon polymer, such as Teflon or polytetrafluoroethylene (PTFE). This material is also able to store energy, but PTFE has a higher dielectric constant and is generally used for higher frequency applications. As with mica, the plates are held in place by a PTFE sheet, but without a central hole for contact terminals.In terms of application field, mica and PTFE capacitors are most commonly used in filters, timing circuits, timers, and oscillators. In converters, they are used to control the frequencies. In radio, they are used in oscillators and AC amplifiers; in television, they are used in RF amplifiers. In computer systems, they are used as components in the digital logic circuits.The working principle of mica and PTFE capacitors is based on the ability of the plates to hold a charge. When voltage is applied across the plates, a charge begins to build up, creating a potential difference across the dielectric. This generates an electric field with a corresponding amount of electric energy, which is stored in the capacitor. When the voltage is removed, the electric field remains, and the stored energy is released.Mica and PTFE capacitors are highly reliable and efficient components, and have remained an integral part of the electronic sector for several decades. Their main advantages are their low cost, high dielectric strength, wide temperature range, and long life. They are widely used in a variety of applications, from high-frequency digital and radio communications to television and computer systems.
