/diy/ - Do It Yourself

My 2 450V 1000µF caps arrived today, the fuckers actually had a charge in them that made a spark when I accidentally shorted them. The spark looked like 20V or so. I plan on using them as filtration caps for a PSU. They say Nippon Chemi-Con on them, and their ratings were around 1.015mF, but I got them from ali so I've no idea if they're legit. Is it common to find proper Japanese brands on ali? They aren't vented, but the bottom insulator around the contacts feels like it might be natural rubber, similar to my Rubycon caps bought from a more reputable source. They're 35mm in diameter, 50mm tall, definitely my biggest caps, they feel like the sort of thing I'd use to power a railgun, though I've no idea what voltage those usually run at, I'm assuming it's lower.

I also got a PCB ruler, 5 no-name 400V 100µF caps, and some IEC sockets among other things.
