Mica and PTFE Capacitors

Mica and PTFE capacitors are two types of dielectric capacitors used in a wide range of applications. This article will discuss the application field and working principle of the MC12FD360F-F, an example of a Mica and PTFE capacitors.

Background

Mica and PTFE capacitors are miniature components that rely on two materials with high dielectric constants – mica and polytetrafluoroethylene (PTFE). Mica is a dielectric substrate that provides a strong electrical insulation layer. PTFE is a synthetic resin that has a very low dielectric loss tangent and thermal resistance. This combination makes Mica and PTFE capacitors an ideal choice for high-stability, durable capacitors suitable for critical applications that require tight manufacturing tolerances.

Application Field

The MC12FD360F-F Mica and PTFE capacitor is a miniature, surface-mount device suitable for use in a variety of applications, including satellite equipment, commercial communication systems, and integrated circuits. Its small size and high operating temperature make it ideal for use in size-constrained circuit designs and narrow temperature ranges. The MC12FD360F-F can also be used in high-reliability and high-stability applications, making it well-suited for use in medical, automotive, and defense industries.

Working Principle

The MC12FD360F-F capacitor works by relying on mica, a type of layered silicate rock, as its substrate. The mica is composed of several thin layers that form an electrical insulation layer between the two active surfaces of the capacitor. A coat of PTFE is then applied to both surfaces of the mica. This material has a very low dielectric constant and, due to its unique chemical structure, allows the capacitor to accommodate a large electric field at high operating temperatures.

When a voltage is applied to the capacitor, the mica and PTFE layers produce a parasitic electric field that stores the charges and release them when the voltage is removed. The capacitor also uses the electrostatic attraction between the two materials, as well as its special co-sintering technology, to produce a strong bond between the mica and PTFE layers. This design allows the capacitor to have a very low series resistance and very low capacitance stability over a wide range of temperatures.

Conclusion

The MC12FD360F-F Mica and PTFE capacitor is a miniature surface-mount device suitable for use in a range of commercial and industrial applications. The combination of mica and PTFE, as well as the device’s special co-sintering technology, allow it to offer a very low series resistance and high thermal stability. This makes it an ideal choice for high-reliability and high-stability applications, such as medical equipment, automotive systems, and defense systems.
