Brief Analysis of Types of High Frequency and Low Voltage Ceramic Capacitors

Capacitor is an energy storage component, which has the characteristics of "straight through, low frequency and high frequency". In order to recognize and identify the capacitors in different circuits, it has given many names according to its role in the circuit. Understanding these names and functions is helpful for reading the pictures. Here is a breakdown of one of them: high-frequency low-voltage ceramic capacitors.

High-frequency low-voltage ceramic capacitors are used in places with low loss and high capacitance and are used where the required temperature coefficient is clearly defined. Such as: resonant circuit, high frequency bypass, temperature compensation, components that control the time constant of the circuit, and coupling components with high stability requirements. High-frequency high-voltage ceramic capacitors are used in high-voltage resonant circuits with UR≥0.63KV or higher, or used in places with low loss and capacitance stability or where the required temperature coefficient is clearly specified.

1) Low-band low-voltage ceramic capacitors, used in electrical appliances that do not require high tgs and capacity stability, such as low frequency, coupling, filtering, decoupling, etc., can also be used as time constant components of control circuits.

2) Low-frequency high-voltage ceramic capacitors are used in high-voltage bypass and coupling circuits with large dielectric constant, large capacity and low loss.

3) Low-frequency low-voltage ceramic capacitor for high-frequency, very high-frequency circuits for broadband bypass coupling, with high dielectric constant, small size, large capacity.

4) High-voltage ceramic capacitors are mostly used in high-voltage bypass with high requirements on withstand voltage. They are characterized by small size, good temperature resistance, good moisture resistance and low loss.
