Help ID WNC(?) cap

[mtl777]

Does anybody know the manufacturer and series of the cap pictured below? It's a 100uF 25V electrolytic and I can see WB which is probably the series and WNC which is probably the manufacturer but I'm not sure. A link to the manufacturer's web site or a datasheet of this cap would be most appreciated. I'd also like to know if this cap is any good for use in the signal path.

Thanks!

Caps are so cheap if you are not sure just but something of known origin.

So it's a Samwha! Thank you so much!

Yeah, actually I already replaced it with a Rubycon ZL. I was just curious about it. Are Samwha caps known to be good quality? I'm wondering because I found it in a high-end ADC unit. Not a likely place to be for a mediocre cap, but maybe the manufacturer was trying to cut cost and the cap is good enough that not many people will notice a difference.

Samwha are a big player, and I wouldn't like to say yea or nay as to how good they are.
They wouldn't be my first choice... but I'm basing that on having worked in the repair trade and seeing a lot of Samwha caps as standard fitment. Often in those cases it's improper circuit design that causes failure so I won't commit on that.

I quite like Panasonics and Rubycons... there what I always order.

Thanks! That's enough of a reason for me to replace them.

I was choosing between Panasonic FM and Rubycon ZL for this position (audio signal coupling). Which one would you have preferred?

[Mooly]

I'm sure if you do a blind listening test you wouldn't tell them apart

For small signal stuff I like Panasonics, the ECA series, partly because I can get them locally,
PANASONIC|ECA1VAM101X|CAPACITOR, 100UF 35V | CPC

If I feel a 105 degree rating is more appropriate I go for these,
RUBYCON|35YXF100MY0811.|CAPACITOR, RADIAL, LOW IMPEDANCE | CPC

Oh these are "for audio" caps. Nice! I wonder, how do they compare with Elna Silmic or Nichicon Muse? I've heard big praises for Elna Silmic but the only problem is its size, too big to fit most of the time when replacing existing caps. If these Panasonic ECA are as good sounding as the Silmic then they are a great find!

Why not the ZL which has lower impedance and higher ripple rating than YXF? For example, for 100uF 25V, ZL has 0.13 Ohms impedance and 405 mA ripple whereas YXF has 0.4 Ohms impedance and 250 mA ripple. For 100uF 50V, ZL has 0.074 Ohms impedance and 724 mA ripple whereas YXF has 0.25 Ohms impedance and 400 mA ripple. The dissipation factors of ZL and YXF are the same across all voltages though.

Lol... because I tend to stick with what I can get locally from C.P.C. as they are within easy reach if I need something quick.

Also have a good range of Pana NHG and FC series and oooh Sanyo OSCONS.

Yeah, the ZL are pretty hard to find especially here in the U.S. Newark has it but not DigiKey or Mouser. I wonder why those big distributors do not carry any Rubycon caps?
