I would also add the following

“United Chemi-Con (UCC)
KYB”

KY
KZE
LXY

This is what I use most of the time what is above

I also use these as well

FC
FR
FM

PW

I will use all of the following brands

Panasonic (2)
United Chemi-Con (1)

Next are equal in how I use these two brands
I will use these two brands when repairing Servo Drive Power Supply Board if the manufacturer has used them on the board if I can find the UF value and voltage and Size Low ESR value

Nichicon
Rubycon

Low ESR =/= Low Impedance

Sometimes you want the Low Impedance...

Default Re: Which series are the low ESR ones?

now i am confused
https://www.badcaps.net/forum/showthread.php?t=12836
on a side not anyone have a screencap of the board referenced in this post (picture looks to have been updated since then)

i can understand that they are not truly equal, but they appear to be close, under what scenario does one come without the other?

Default Re: Which series are the low ESR ones?

When I look for capacitors I look at ESR value and Low Impedance value but I would not look for lowest ESR resistance value i look for something in the middle of the values that are listed

That is why I use these series that I listed before and I have not really had any problems with doing it this way ( switching power supply’s)

United Chemi-Con (UCC)
KYB”

KY
KZE
LXY

Lower impedance is pretty much Lower ESR

Search for "[manufacturer] capacitor chart" in Google

Ex
Panasonic : https://industrial.panasonic.com/cdb...E0000COL92.pdf



Rubycon : http://www.rubycon.co.jp/en/catalog/...RIES-CHART.pdf




Nichicon : http://nichicon-us.com/english/produ...ini/index.html (hit diagram search)
