Common problems with high voltage ceramic capacitors

High voltage ceramic capacitors are one of the common electronic components in life, and are used in high stable oscillation circuits.

What is the role of high voltage ceramic capacitors connected to 220V?

Answer: It is mainly used for filtering, filtering out high frequency AC components.

What is the difference between ordinary ceramic capacitors and Y2 capacitors?

answer:

1. Porcelain capacitors are mainly for high frequencies. High voltage ceramic capacitors depend on the application. Typical effects can eliminate high frequency interference.

Advantages: 1) The capacity loss has high stability with temperature and frequency. 2) The special series structure is suitable for high voltage and extremely long-term working reliability. 3) High current climbing rate and suitable for non-inductive structure of high current loop.

2. Y2 capacitor belongs to Fan Tao of safety capacitor. It is used in such a situation that after the capacitor fails, it will not cause electric shock and will not endanger personal injury.

3. According to the national standard test, the ordinary ceramic capacitor is 1.5 times the rated voltage + 500V, while the rated voltage of the Y2 capacitor is 300V, and its test withstand voltage needs to reach 2500VAC.
