Mica and PTFE Capacitors

The mica and polytetrafluoroethylene (PTFE) capacitors, known by the part number CDV30FF912JO3F, are dielectric capacitors with a ceramic and polytetrafluoroethylene (PTFE) coat that provide reliable performance and long-term reliability while operating in high frequencies. These capacitors offer excellent frequency characteristics, low levels of acoustic noise and vibration, and high capacitance with a small volume.

Application Field

CDV30FF912JO3F are ideal for radio frequency (RF) applications such as high-frequency amplifiers, DDS circuits, mixers, oscillators, and balancing circuits. They can also be used for pulse circuits, linear voltage regulators, speed controllers, and voltage regulators. CDV30FF912JO3F capacitors are also commonly used for medical equipment, measurement equipment, and protection circuits.

Working Principle

The capacitance of CDV30FF912JO3F is determined by the type of material and the size of the dielectric used. The dielectric selected for CDV30FF912JO3F is mica, which is a naturally occurring mineral, and polytetrafluoroethylene as the film. Mica provides the required breakdown voltage for stable use in high voltage circuits whereas polytetrafluoroethylene is self-healing, meaning the electric field is released as soon as the voltage falls below the dielectric\'s breakdown characteristics. This self-healing property is what makes CDV30FF912JO3F capacitors more reliable for high frequency applications.

The operation of CDV30FF912JO3F capacitors requires the dielectric layer to be placed between two conductors or electrodes. When a voltage is applied, the dielectric layer will be affected by the voltage, allowing current to flow through the circuit. The amount of current that is able to flow through the circuit will depend on the type of material and the size of the dielectric layer used. The two electrodes of the CDV30FF912JO3F capacitors are made of mica and PTFE, giving them excellent frequency characteristics and a wide range of operating voltages.

The most important function of the CDV30FF912JO3F capacitors is to store energy and then release it when necessary. When the capacitors are fully charged, they store energy as an electrostatic field between the electrodes and the dielectric layer. When the capacitors are discharged, the energy stored in the capacitors is released in the form of an electric current, which can then be used by the circuit it is connected to.

CDV30FF912JO3F capacitors are also known for their low levels of acoustic noise and vibration. This is because of the high dielectric loss tangent (DLC) of the mica and polytetrafluoroethylene used for the dielectric. The low DLC eliminates the possibility of any energy to be lost due to noise or vibration, making these capacitors reliable for operation in high-frequency applications.

Conclusion

CDV30FF912JO3F mica and polytetrafluoroethylene (PTFE) capacitors offer reliable performance at high frequencies. They have excellent frequency characteristics, low noise and vibration, and a wide operating voltage range. They are ideal for radio frequency (RF) applications, medical equipment, measurement equipment, and protection circuits. The self-healing and high DLC properties of the mica and PTFE make these capacitors reliable for long-term performance.
