Help Identify Capacitor Specs

[jolson1989]

Hi guys,

I'm not using these capacitors in a computer, but you guys seem to know your caps, so perhaps I'll find some much needed help here. I need to know the temperature class of capacitor these guys fall in. I got the values, but I need to know if they're COG/NPO or X7R.

I've tried google image searching and searching the specs to death. The closest I can maybe seem to find is that the ones marked with the T might indicate the material as being polythereftalate according to here: http://mediatoget.blogspot.com/p/capacitor-labels.html Does anyone know what the dotting system means or how to interpret it?

The only reference I could even find to someone else having trouble with the dot system used on the red guys is another forum post here: http://www.diyaudio.com/forums/parts...ting-dots.html, but they never got beyond telling him the cap value.

Does anyone know what brand/company logo is on the blue guy? Or what the M1E indicates. I can't find anything about the E mostly, which is the part I really need.

Thanks for all your help! Let me know if you need/want more info.

What are they for use in what voltage do they run at - have they failed? dont look burnt chipped or cracked

Re: Help Identify Capacitor Specs

They haven't failed, I just need to categorize them based off of their temp specs.

The red guys I have no clue as to the voltage, but the 1 in the middle of the blue usually indicates 10V, which is fairly low for most capacitors of its value. I assume the red is in the 10 to 100 V range.
