Default What brand cap is this (black SM-series)?

Anyone know the brand of this capacitor?
It has an 'M' on it but not in the usual Matsushita/Panasonic font.
I find them in lot of A/V gear from the 80's and early 90's.

In this case (M) indicates the tolerance level, which is 20%.

The shield logo is Nippon Chemi-con: http://www.chemi-con.co.jp/e/index.html

Overall, Nippon Chemi-con capacitors are very reliable. They had a few dud series, but none that are likely to turn up in AV equipment.

SM isn't on the site any more, as it's probably an older series. If their naming schemes are consistent, the closest modern replacement is probably SMG, which is an 85C general purpose capacitor: http://www.chemi-con.com/files/SMGSMG%20H9.pdf

I see a lot of Korea Chemi-con as well in older AV equipment. Korea Chemi-con is (was?) a related company with a very similar shield logo, only with a dot in the center. Korea Chemi-con is not as well regarded, but I haven't seen any failures. Then again, I don't work on AV stuff very often. I'm not sure of the history, but I think they're related to Samyoung, which does turn up occasionally in computers with occasional failures.

thanks very much.
I never saw that as a shield, just a box!
These parts did not fail, and I have never seen any fail except some leakage over 25+ years. I posted here because I thought someone would know and others might like to know as well. Thanks.
