Too lazy right now, but these're small D5 mm (5 or 7 tall), 22 uF/50 V, all black, PKSM, 105 C, 1512 manufacturing date, nothing else.

It's a little update, they used to use some no-name crap in there (Jiang Hai, Jamicon etc.) 22/50 for 85 C max, but still, replaced them all just to be sure with Chemi-Cons LEs and KMGs (there are two spots where it does not like LEs). One of them already had 3times the ESR of the rest…and I don't particularly trust IC, especially with this they're showing.

Haven't them been like bought by CDE? It looks to me they changed almost ALL of their series since I've been going through them couple years back.

One oddity I noticed, looking through IC's products diagram, is that IC's series names are 3-character, not 4-character. So custom? Counterfeit? Quien sabe?

Must be custom than. I took another unit as this one likely has bad CPU or something around the way. This time the one in the usual spot was totally done and couple others were bad too so I'll be replacing them as usually with something I trust.
