Mica and PTFE Capacitors

Capacitors are useful components in electronics; they are widely used in circuits to store electrical energy or charge. Examples of capacitors include ceramic, electrolytic, mica, and PTFE capacitors.

Mica and PTFE capacitors are two types of capacitors sharing similar characteristics. Generally, mica capacitors are made of metalized mica, while PTFE capacitors are made of metalized PTFE film. Both mica and PTFE capacitors exhibit high reliability and are typically used in high-precision portable equipment, medical equipment, aerospace systems, and so forth. The CD4CD090DO3F is one of these capacitors.

Application Field

The CD4CD090DO3F is a mica-and-polytetrafluoroethylene (PTFE) capacitor with a capacitance value of 9pF and an operating temperature range of -55°C to 125°C. It is commonly used in electronic circuits for micropower transmitters, regenerative feedback control systems, signal filters, and other applications. For instance, it can be used to improve signal-to-noise ratio and charge-boosting performance. The main benefits of the CD4CD090DO3F are its low-loss characteristics, stability over a wide temperature range and high frequency range, and low insertion loss.

Working Principle

The CD4CD090DO3F is a combination of two capacitor plates, an external metalized PTFE film layer, and an inner metalized mica layer. This design gives the capacitor better dielectric characteristics than traditional electrolytic capacitors. The PTFE layer provides a low dielectric constant, which helps reduce the distortion caused by capacitive reactance in DC circuits. The mica layer acts as a heat-resistant insulator, improving temperature stability, and increasing durability. The combination of these two layers also helps reduce ionic surface currents, further improving its reliability and resilience.

The CD4CD090DO3F operates by charging and discharging the capacitor\'s plates. When a voltage is applied to the plates, the electric field that is generated causes the capacitor\'s plates to become charged. When the voltage is removed, the capacitor\'s stored energy is discharged, and the capacitor\'s plates return to their uncharged state. The CD4CD090DO3F is able to quickly store and release energy, making it an excellent choice for a variety of low voltage electronics applications.

Conclusion

Mica and PTFE capacitors are reliable, long-lasting components used in many applications. The CD4CD090DO3F is a combination of two different types of capacitors, mica and PTFE, that offers exceptional performance. Its low dielectric constant, excellent temperature stability, and long-term reliability make it a cost-effective choice for a variety of electronics applications.
