Can the ceramic capacitor on the high voltage board be removed?

High voltage ceramic capacitor generally refers to ceramic capacitors above 1kv, mainly using high-permittivity capacitor ceramic barium titanate and titanium oxide extruded into a round tube, wafer or disc as a medium, and silver plating on ceramics by infiltration The upper is made as an electrode. Advantages: small size, high pressure resistance, stable performance, no oil, no gas, no pollution, etc.

So, if there is no suitable capacitor, can the ceramic capacitor on the high voltage board be removed?

There are usually 1-4 high voltage ceramic capacitors on the high voltage board. The output end of the high voltage transformer should not be connected in parallel with the ceramic capacitor. The ceramic capacitor has the function of blocking and coupling, and will not short circuit? Does not short circuit. Capacitors are separated by straight through, small capacitors pass high-frequency current, and a ceramic capacitor in parallel with the transformer output can be regarded as short-circuiting the high-frequency current. Filter out high frequency signals and reduce high frequency interference to other circuits or electrical equipment.

Example: Generally, a small capacitor is connected in parallel to the starter of a fluorescent lamp. If this capacitor is not combined, wireless devices such as radios not far from the fluorescent lamp will have a strong interference sound. In addition, the replacement of the ceramic capacitor on the high-voltage board must also be replaced with the same capacity, withstand voltage or larger, to ensure that there are no problems.
