Which type of capacitor should be used at the output of flyback converter and in the auxiliary winding? Output voltge is 12 volt and capacitance is 280 uF. For auxiliary side voltage rating is 375 volts and capacitance value is 6.35 uF

 

Low ESR (Equivalent Series Resistance) electrolytics are often used for that and should work for you. Be aware of the often-overlooked ripple current rating of the capacitors you select.

I am using it after rectifier that is as an input bulk cpacitor. My doubt is what type of capacitor I should select for output across load?

 

That was what I was I addressed in the (slightly revised) post #2.
