Alibaba Capacitors
« on: May 18, 2022, 11:59:25 AM »
Anybody have any knowledge/experience with these oil-filled things? Still fiddling about with the DC primary design and I noted these 2uF 10KVDC caps as a possible for DC smoothing in a single phase design from Richie Burnett's website.

https://www.alibaba.com/product-detail/Capacitor-2uF-10KV-High-Voltage-Pulse_2007844335.html?spm=a2700.7724857.normal_offer.d_title.62d82920yb7ruK


They would be running as smoothing caps at a max 7.1KVDC - (5KVAC x 1.414) smoothing at 5-20KHz for one of my HF transformers.
Cheers / Robert

The listed price is way lower than the actual price, have you tried contacting them?
I'm sure they function fine but capacitors like that will generally be $250-$350 even from China.

I not long ago purchased what was listed a "10KV 200uF" capacitor, but the answer I got was, the listing is wrong and the price was for a 1uF. It was $250, the 200uF was $5500. Too good to be true usually is.
