I just scored some great 600v 75uf poly caps for a power supply I’m building. They were only $4 each at Apexjr. I’m not affiliated but just had to share because we can all use good high voltage ps caps. Only thing is they have short leads but really who cares at four bucks?
From the image its a pulled chinese cap from Foshan Shunde Chuangge Electronic Industrial Ltd, ( cgegd.com ), the MKP-LM range (which now appears to come in a rectangular case). You can pick such stuff cheaper on AliExpress I reckon.

These are not pulls, they are not pcb mount either, they are axial brand new caps. I’ve checked Ali and found nothing this big at this voltage for near this cheap. They beat the hell out of electrolytic caps. Can’t please everyone!
They come in trays of 12 but he sells any quantity.
The comparable caps cost from 18 to 22 each at the major suppliers so $5 is a great deal and better than series electrolytics for under 600v.

We got the same thing going on with Arcotronics locally, i think i got some 10uF 550VDC DC-Links for 2,50 US each.
I reckon after shipping and cost and the time it takes to get to you from China it would be better to go with these but, opinions may vary. I don’t like PCB mount leads either. Like I said, the major suppliers charge about $20 for the equivalent cap here in the US. Plus you are giving business to a small business which is always a good way to spread the wealth. But, do as you wish, it’s a free world for now anyway.
X type for coupling ok, I use them also. But to use in mains system, so many fails on this type.
