AC voltage ratings for capacitors
In various circuits intended for use with 230-250 V AC I''ve seen capacitors labelled as "400V" (Examples: 1, 2) When I look at Capacitor specifications, they often give separate AC and DC ratings. For example: X1 440 VAC 1000 VDC X2 350 VAC Y2 400V (but package confusingly marked "Y2 (330V~) X1 (440 V~) ..

5.08 Series Connection of Capacitors
Now, as we did in the case of parallel connection, we are going to simplify this circuit by replacing all these 3 capacitors in series connections with a single capacitor. And let''s call it as C equivalent, so that that single capacitor will do the same job in the circuit that these three were doing in series combination.
Buck converter with switched capacitor charge compensation for …
As microprocessor currents exceed 500 A and slew rate reaches 1000 A/µs, increasing the decoupling capacitance on the motherboard to ensure normal operation of the microprocessor is inevitable because of the limited response capability of the voltage regulator. However, the area of the motherboard used for capacitors is usually narrow. …
