Default Würth Elektronik Electrolytic Capacitors Official Thread

Not a lot of information out there on this German company's electrolytics. They have a family of seven different types:

WCAP-ATG8: General Purpose, standard temperature
WCAP-ATG5: General Purpose, wide temperature
WCAP-AT1H: Long Life, wide temperature
WCAP-ATET: Long Life, very wide temperature
WCAP-ATLI: Low Impedance, wide temperature
WCAP-ATUL: Low ESR, Long Life, wide temperature
WCAP-ATLL: Low Impedance, Long Life, wide temperature

They generally sell at lower prices than their Japanese competitors. This would be a good place to discuss personal experience with the product. I have an upcoming recap job on a Yamaha cassette deck and I have ordered Wurth caps for the job. I will follow up when complete.

Just as a comparison, I have put together a Wurth to Nichicon cross reference:

ATG8 --> VR
ATG5 --> VZ
AT1H --> PV
ATET --> BT
ATLI --> PJ
ATUL --> ?
ATLL --> PW

I've always wondered about Wurth caps myself. I've been seeing them get advertised a lot on Digikey lately, along with other non-cap products they make.

That said, I still trust the old Japanese brands more than anything else. Though recently I noticed that many of them have moved production to China. For example, I just got some Nichicon HE not too long ago all of which had a COO (Country Of Origin) as China. Let's hope the Japanese are keeping a close look on those Chinese factories.

Well, I completed my re-cap job with the Wurths. Everything went fine and unit is working great. We'll see how things go from here, but I've used a lot of Wurth products in the past from automotive to electrical and have never had any issues. What I do know is that the job cost 1/3 less than going with similar Nichicon caps.

Good!

Keep us posted (if possible) if anything happens with them. It's always good to have a bigger list of known good caps to work with.

Did you use the WCAP-ATUL series?
I was looking at using some Wurths in a power supply recap...
Do you think the WCAP-ATLL or ATLI series would be good enough where the ATUL is not available?

Wurth are re-branded Taiwanese caps. Probably either Lelon or Teapo.

Their polymers are also probably re-branded Taiwanese. Taiwanese polymers are of adequate quality compared to Chinese polymers, which should usually be avoided.

I hope to address that in a seperate thread in the future. Lelon makes pretty good polymers, but their electrolytics should be avoided. I would also avoid Wurth electrolytics.

I used the ATLL series which is, I believe, comparable to Nichicon PW.
