Mica and PTFE Capacitors

Mica and PTFE capacitors have been used for decades in telecommunications and electronics applications, operating in the various frequencies up to 1 GHz. Today, they are still very prominent in many applications, due to their excellent electrical properties and stability when used in temperature cycling and other harsh operating environments. The CMR05E330GODP is a specific type of mica and PTFE capacitor. It is a small form factor, high frequency, high performance miniature multilayer ceramic capacitor, suitable for many diverse operations within the frequency range of 0 to 1GHz. It is primarily based on Mica-PTFE dielectric construction with an Epoxy-Dipped termination. Depending on the product, the CMR05E330GODP features an operating temperature range of –55°C to +125°C, and impedance ranges from 27.5 to 1647 ohms.

Application Field

The CMR05E330GODP finds its place in a wide range of applications, mostly within telecommunication, biomedical, and automotive electronics, given its excellent electrical properties and stability. Common applications are found in oscillator circuits, such as in frequency synthesizers, oscillators, and resonant circuits; filters and dampers used to attenuate unwanted noise and interference within transmissions; and in matching and tuning circuits, like impedance matching networks, baluns, and ceramic chip antennas.

Working Principle

The working principle behind this type of capacitor is also based on that of conventional dielectric capacitors. The CMR05E330GODP capacitor has an alternating arrangement of two different types of dielectric: Mica and PTFE. Mica is an insulating material, and PTFE is a polytetrafluoroethylene, a fluorinated plastic with superior insulation properties. The Mica and PTFE layers form alternating plates between two metal electrodes, with the PTFE layer providing a high dielectric constant, while the Mica dielectric provides the excellent stability and superior mechanical strength. As a result, the CMR05E330GODP capacitor is presently one of the most advanced ceramic capacitors on the market, offering high performance, stability, and reliability in its operations.

Conclusion

The CMR05E330GODP is an advanced type of mica-PTFE capacitor, offering many superior electrical properties for various applications in electronics and telecommunications. Its two-layer arrangement of mica and PTFE dielectric makes it reliable and stable when used in temperature-cycling, and with its high performance and frequency ranges, it makes a perfect choice when looking for a versatile capacitor for many diverse applications.
