the choice of input capacitor for PFC

[dcj50105]

pfc input capacitor

Hello! everyone,
Is anyone available to tell me which kind of the capcitors is the best to be used for PFC's input capcitor, if possible ,please tell me the details of its manufactuer, whose capacitor is best to be certificted.

Input capacitor? Do you mean for EMI filtering on the input or do you mean the input capacitor to the rest of the circuit which will be the boost capacitor of the PFC block. The boost capacitor should be of a type that can handle high ripple current, so something with a low ESR value to reduce heating in this cap.

If you use in pre-rectifer,you should use safty capcitor,If no,use no-polory cap
