Mica and PTFE capacitors are among the few ceramic capacitor components still used in the advanced circuit industries. However, one of the most popular and widely used models of these capacitors is the CD19FC622GO3. It stands out for its relatively small size, yet its amazing level of energy capacity. Let’s take a look at the application field and working principle of the CD19FC622GO3.

The CD19FC622GO3 is a polyacrylate-encased mica and PTFE capacitor. The maximum capacitance is from 0.20 to 10.0 microfarads, with a rated voltage from 500 to 5000 volts. It has a wide range of applications, including DC blocking circuits, DC filtering circuits, power supply circuits, high frequency circuits, and telephone line circuits. It can also be used in high-frequency communication equipment, radio and television transmitters, power amplifiers, TV receivers and other instruments in high frequency applications. It is also an ideal solution when a small capacitance with high rated voltage and high insulation resistance is required.

When a voltage is applied to the capacitor, a parallel plate is generated in the capacitor. The two plates are separated by an insulating material, usually mica. With the applied voltage, the electric field concentration of the mica between the two plates increases, resulting in a higher dielectric constant for the capacitor. Thus, the capacitance of the capacitor is increased. When used in microwave circuits, the mica-encased capacitor has the advantage of low inductive and its high insulation resistance helps to effectively reduce parasitics.

The CD19FC622GO3 also features a variety of special functionalities. Some models feature a built in ohmic resistor, so that they can be used as self-forming components. The built in ohmic resistor helps to reduce the contact resistance of the component nodes. Others feature an adjustable construction that allows for the value of the capacitor to be altered. This is useful in filter networks and other systems where it is necessary to adjust the capacitance of the capacitors to allow for varying amounts of current to flow through the circuit.

The PTFE coating also provides additional protection for the capacitor\'s components. It helps to dissipate high temperatures generated by high frequency applications, ensuring that the components of the CD19FC622GO3 are safe and secure. It also helps to reduce the dielectric losses of the product, making it an efficient and reliable component for use in high frequency applications.

In summary, the CD19FC622GO3 is a highly popular capacitor choice for use in advanced circuit industries. It is a polyacrylate-encased mica and PTFE capacitor with a wide range of applications in DC blocking, high frequency, power supply and telephone line circuits. The CD19FC622GO3 also features a number of special features, such as an ohmic resistor and adjustable capacitance, as well as PTFE coating that helps to dissipate heat generated during operation and minimize dielectric losses. These features make the CD19FC622GO3 a very reliable and efficient component, perfect for use in advanced electronic applications.
