Appearance of Y capacitor is mostly blue, generally marked with the safety certification sign (such as ULVDEEN CQCU KC logo) and voltage AC300V or AC400V words. However, its real DC withstand voltage is as high as 4000V. It must be emphasized that Y capacitors are not allowed to be replaced by ordinary ceramic chip capacitors.
The Y capacitor grounding plays a filtering role, and the limit of Y capacity based on leakage current can not be too large. Y capacity from 10PF to 10000PF, different voltage specifications, the corresponding characteristics are different, the error is also different y capacitor in different parts of the size.Appearance of Y capacitor is mostly blue, do not use the ordinary ceramic chip capacitor to substitute.
