how wide are the 1800uf caps? 8mm or 10mm

they dont always do that - which is actually worse because you need to note the details before you pull the old caps - or go searching for pictures afterwards.

Funniest of all that K58 Kemet caps survived...

And the board worked for a long time... You know... 3 days...

So, after desoldering caps what I got is:
3 died panasonic(probably not) caps, each of them lost half 800 uF of their capacity(Finally got at least LCR-T4), and got high ESR
1 out of 4 Kemet caps died on desoldering, as one output lead desoldered(or what it has done) from the cap too. Other Kemet caps survived and still got good ESR in range from 0.07 to 0.11 and 360-380uF capacity

a polymer with 0.11ohms sounds so wrong!

they are 330uf 6.3v, will check the datasheet for these Kemet A758

So from datasheet it says ESR at 100 kHz 20°C is 16 mΩ

**stj** · 06-06-2021, 12:45 PM

0.016 is a lot less than 0.11

yea I know

also, btw, can you give me a link to a poly caps pls

**stj** · 06-07-2021, 01:23 AM

best i'v found in 8mm so-far is 1000uf, but i'm still looking

I think this is would be hard one, as polymers are more wide and more low, so I found only 10mm 1800uf one...

**stj** · 06-07-2021, 05:24 AM

1500uf will be fine, but i suspect we wont find more than 1200uf.

**mockingbird** · 06-14-2021, 01:25 PM

Of course they're fake.

I have never seen Panasonic FL sold to the masses that were genuine, nor are they even manufactured any longer.

**brethin** · 06-14-2021, 11:47 PM

You got faked, keep crying.
