Ceramic Dielectric Variable Capacitor

Ceramic Dielectric Variable Capacitors are a type of capacitor that falls under the supply class of Capacitors in the supply group of Electrical and Electronic Equipment Components.

These capacitors are designed to have a variable capacitance, meaning that their capacitance value can be adjusted or tuned according to the application requirements. They are commonly used in electronic circuits where precise tuning or adjustment of capacitance is needed.

The dielectric material used in ceramic variable capacitors is typically ceramic, which provides good stability and reliability. The capacitance value can be adjusted by rotating a shaft or a screw, which changes the effective area of the capacitor plates.

Ceramic variable capacitors are widely used in applications such as radio frequency (RF) tuning circuits, oscillators, filters, and impedance matching networks. They are known for their compact size, high Q factor, and good temperature stability.

When selecting a ceramic variable capacitor, it is important to consider factors such as the desired capacitance range, voltage rating, temperature coefficient, and mechanical dimensions to ensure compatibility with the specific application requirements.

Overall, ceramic dielectric variable capacitors are essential components in electrical and electronic equipment, providing precise tuning capabilities for various circuits and applications.
