samwha cap question...

[eppidrummer]

New here and kind of new at replacing caps. Have recapped my 2nd dell board will complete success but still not sure on all the cap terms.

I have a bad cap:
Samwha 2200uf 10v WL
I dont want to place an order for just 1 cap and happen to have a:
Rubycon 2200uf 10v ZL on hand.
My question is about the "WL" on the Samwha cap.
can the Rubycon cap replace this even though the Rubycon has an ZL value?
Both caps have the same dimensions.

Guess not really sure what the WL value means.
Thanks for any help!

Re: samwha cap question...

The Rubycon should work. The WL is the series of the capacitor made by Samwha.
If you check the datasheet on the Samwha WL series, you'll see that the ESR
of a 2200 uF 10 V capacitor is 50 mΩ and the maximum ripple current is 1400 mA.
The Rubycon ZL 2200 uF 10 V capacitor has a 21 mΩ ESR and a maximum ripple
current of 2360 mA. You can find the datasheet on the WL at

and the datasheet on the Rubycon ZL series at

Re: samwha cap question...

Correct. - A ZL is an upgrade.
Want Ripple the same or more.
Want ESR the same or less.

For Samwha WL even just Panasonic FC would be an upgrade.
FC are common and usually inexpensive.

Gotta start somewhere.
6 years ago I didn't know what ESR was.
