ESR values of ASC X386s capacitors anyone?

[tonescout]

Has anyone measured or got the specification for the ESR of the ASC X386s capacitors, I have asked the manufacturer and after 2 weeks of 'sorry we are taking so long, technical is busy' I thought I would ask here. I want this to confirm a PSUD2 simulation to select the sizes to purchase.

Thanks!

For those who are interested I finally got this back from the manufacturer for a couple of sizes.


X386S 30 10 440 VAC
At 60Hz, 32.631 mΩ
At 1kHz, 19.113 mΩ
At 100kHz, 18.259 mΩ

X386S 50 10 440 VAC
At 60Hz, 19.579 mΩ
At 1kHz, 11.468 mΩ
At 100kHz, 10.955 mΩ

Good to know, thanks to share.

my brother has a simple ESR meter so when I get the final selection I will test them all and post here too.

That's will be better to reconfirm the manufacturer values, thanks for your time.

ESR doesn’t matter much at low frequencies. Only when you get into switching power suppliers does ESR matter.
