I can’t seem to find a way to decipher this capacitor

[GitouMan]

Hi everybody, I’m about to refurbish my euphonix system 5 system. First on the bench are my sc264 pc and the df66 audio dsp unit. When preparing a mouser list for the df66, I came across what I believe is a tantalum polymer cap. However I’m unsure to decipher the value. I’m thinking the 220 9750l D stands for formfactor D, 220 uf 6v (0L) the 975 I’m really clueless about. The same problem with the 100 80mbs D cap. Any direction, would be highly appreciated!

No chance of measuring the voltage across it, with the unit powered up?

"100" on a polymer tantalum takes my mind towards 100uF.

Seems those may well be some series of Panasonic SP-Cap polymer aluminium caps. The small "d" is the voltage rating, corresponding to 2V.

Use the filters in this last link (voltage, case size) to narrow the product list down to the most likely suspects, and find compatible replacements going from there.

Why do you feel you need to replace (at least) those two, though?

Thank you very much, this got me on my way. Looking at the datasheet maybe not needed to preventatively replace

If anything, the liquid electrolyte caps would be more prone to "wearing out" (higher ESR, more self-heating etc).

These single-digit-milliohm solid electrolyte caps should last virtually forever anyway, but what do i know? Unless you've had issues with freezes / reboots (rated at 2V, these are likely filtering some digital supplies), i wouldn't bother with them.

 

[GitouMan]

Great advice. Thanks for your support. Will not exchange these and keep focus on electrolytics

Parts vendors like digikey and mouser often show images of components so search out you best guesses until you find images of the same parts.

I just went with a google image search for "tantalum polymer", and among the first 10 or so images (renders, mostly) there was the first page of a Panasonic datasheet with identical structure of the markings.

 

[GitouMan]

Didn’t know about that function in google search. Thanks a lot will experiment with it to get up to speed!

Could desolder and measure capacitance... unless cap is gone, of course.

This is true except images may or may not be correct and they often have a tiny disclaimer under the image.

The other numbers are date codes and/or factory location

Might help to, y'know, sometimes consider reading through the whole thread first..?
