Blocking capacitor examples

WebSep 23, 2016 · CB is blocking capacitor and can be anything between 470n and 1u. But voltage rating of the cap is important and should be at least half of maximum DC bus voltage. For example, if the input varies between 185 and 265Vac then VIN (max) = 370VDC. So CB can be a 1u/250V.
