Kamet made that style and they are the T310 series. The MTAC seems like a AVX part number but it's hard to tell at times. Could also be a Mallory number too. I'm looking for my old part cataloge for the late 70-80 when I find it I think it will help.
Last year I unreeled 6 pallet of them and filled an entire Gaylord full of them.

I thought I had seen something about them being made by Union Carbide (trying to find my notes on this). I think KEMET was sold to a management group from the original UC division. Thank You for your info, gives me a direction to go with. I wish I had a gaylord full of tantalum caps. Was reading your post on the G.R. forum and reminded me to ask you, your the man!

Yesterday I broke down eight industrial X-ray monitors, these were made between 1980 and 1984. I'm going to show a couple of pictures here of the tantalum capacitors. Interesting thing about these monitors was the fact that they had just about every type of capacitor that is made. This included 17 tantalum and 11 silver mica capacitors. If someone wanted to test their knowledge on how many different capacitors they could identify, these monitors would be a challenge for the most experienced tech. Maybe later I'll post a breakdown of the monitors in another thread.

This picture shows part of a circuit board, there is six capacitors that can be seen. Can you spot the tantalum capacitors? There is two different type of tantalum capacitors, if that helps!

CORRECTION: SEVEN CAP's

Let me take a guess. All four silver ones are TCs?

Maybe a picture of one type will help, same board just a different location.

These monitors had three circuit boards, a analog, digital and a video control board. This is a picture of a section of the analog (output side) with 6 TC's.

Correction only 5 TC's, I edited photo and cut off one by mistake!

There is no TC's in this photo, just a little bit of gold for the bucket!

This is a picture of the CRT (THE SMALLEST I'VE SEEN).
[IMG][/IMG]
The picture face is just 3" x 3 1/2", made by Ball Electronic Display Division (model CD5).
In some old video cameras(I think it was video cameras) I've found them as small as 1.5" x 1". Wish I had one around for a photo but...Originally Posted by bigburtchino

The board in this photo is out of a OscarVision VHS/TV/Monitor combo. I found three TA on it. Can you?
Hope you didn't find three because the third one is hidden in pic. It's at upper left behind AL heatsink which is just in front of a small transformer. The other two are orange epoxy.
Since I was logged in to Photobucket, thought I'd post pics of TA caps that I had posted previously in another thread. Just so we could have several diff types in one place in this thread.

Flinthills - On your hermetically sealed TA's do you know who made them? I still looking for my first multi colored TA's from what I have learned I think those are from Europe.
I don't know who made them off hand. I'll get some numbers and/or names off of them to post here.

I just save the little yellow block looking ones I got half a baby food jar right now.

The multi colored ones are older poly coated ones. The colors are like the colors from resistors they mean something.

I buy Tantalum Capacitors and offer other services. Check out my thread for more info.

Maybe this will help clear it up a little more.

Most all are mkd Sprague or TASM. I don't know who or what TASM is but that's how they're marked.

Cornell Dubilier Part Numbering System - Type TAS Solid Tantalum Capacitors. TAS is the series and not sure what the "M" is? I originally thought the capacitance tolerance, but I have found caps with the letter "K" on them as well. TAS is defiantly made by Cornell Dubilier now.

I think the old TAS M capacitors were originally made by Mallory and latter on Cornell-Dubilier acquired the TAS series capacitor (2002?). So TAS M are made by Mallory before 2002. After 2002 made by Cornell-Dubilier (CDE). With all the mergers it can get confusing trying to determine who made what when!
