Screw-type high-voltage ceramic capacitors (also referred to as bolt-type high-voltage ceramic capacitors or "Doorknob Capacitors") are widely utilized in industrial and power system environments-settings where reliability requirements are exceptionally stringent-due to their characteristics such as high voltage endurance, high current handling capability, low loss, and high stability.
High-Voltage Power Supplies
The application of high-voltage ceramic capacitors in high-voltage power supplies constitutes their most critical area of use. Since high-voltage power supplies demand the utmost stability in input voltage-while simultaneously striving to achieve the highest possible output voltage and efficiency to meet load requirements-high-voltage ceramic capacitors serve as effective input capacitors. In this role, they effectively regulate input stability, significantly boost the output voltage of the power supply, and consequently enhance the overall efficiency of the power system.
Medical Devices
The field of medical devices imposes some of the most rigorous demands regarding component precision and reliability. Given their attributes of high reliability, stable capacitance values, and low loss, high-voltage ceramic capacitors are extensively employed within medical instrumentation. Common applications include devices such as electrocardiogram (ECG) monitors and ultrasound probes.
Radio Communications
In the realm of radio communications, the application of high-voltage ceramic capacitors is primarily concentrated within high-frequency circuitry. High-frequency circuits necessitate capacitors that exhibit stable capacitance values and minimal loss to ensure the overall stability and reliability of the circuit. Owing to their exceptional high-frequency performance, high-voltage ceramic capacitors have emerged as essential components within the field of radio communications.
