Help me identify these Caps! (hamfest find)

[ashevillebob]

Yeah, I'm guilty. I go to the Hamfest in Shelby NC every year and really don't know what I'm looking at half the time, but I end up wheeling home a milk crate full of treasures just the same.

These caps have been in the basement for at least 4 years in a grocery bag. I think I have about ten altogether. They all have a piece of styrofoam taped to the screw side(positive side?).

I thought I could use them if they are close to 2.2uf but I can't figure out who makes them or the coding for that matter. I'm hoping they are PIO but more likely are full of PCBs. They have no name or logo.

Coding reads: 84411
612G
47404L15
5910-
727-2268

Anybody got an idea?

Here's some info, the 5910 is the Federal Stock Class number for capacitors with hazardous materials. Did you mention PCBs? They are (were) probably military. Still searching for more info.

84411 is the manufactures code. In this case it is TRW capacitor division. And I would guess the value to be .47 uFD (474=47 and 4 zeros)

[HollowState]

5910-727-2268 is the federal stock number. There is something called Fed Log that is a master list of all items in government inventory. I don't have a set of the discs but I think it's possible to access it on line. However that may involve downloading script programs that I don't feature doing.
You also have to pay for it. http://www.defensedata.com/

I guess the best thing to do is treat them as .47uf and only use them is low power amps like T-amps since finding the voltage rating may involve additional cash outlay. I probably have a buck in them and there not leaking so I guess i should listen to them and go from there?

Thanks for the help Hollowstate!

[ashevillebob]

Maybe the O4L15 is 450v at 15%(L being roman # for 50) which means I could try them in tube amps. (Due to there age I think they would have only come from tube equipment anyway). Is my guess of polarity correct or are they possably non-polar? I would hate to have one pop in my face and have to be scrubbed down by a hazmat team. The screw mount would ground them to the frame I think in some applications, leaving the center pin +?

I have a copy of the Federal Logistics Database (FEDLOG) 2002.

That NSN (National Stock Number) appears to no longer be in the version of the database that I have (unless the country of origin is not the USA and I therefore searched for the wrong NSN). The full NSN would actually be 5910-xx-727-2268, where the xx denotes the country of origin, with 00 being USA, I believe. The NIIN is also sometimes used, and is just the NSN with the 4-digit FSC (Federal Supply Class) code prefix omitted, or probably 00-717-2268 in this case (assuming the "00" is correct).

I also searched for the CAGE code, and got this:

Supplier Data Response

I then had it show me all part numbers for that CAGE code and picked one that was similar, since the one you have (part number 612G47404L15) was not listed. The Characteristics Data screen for part 612G47223W3 is shown below:

Then I looked at a part number that had an Lxx suffix, which I thought might be closer to what you have (I don't know if it really is or not). So here's the data for part number 61310502L16:

Good luck!

Tom,
This info is amazing!

The closest measurement is the center choice
(part number 61310502L16).The only measurement that is off is the body height lying on its' side (diameter). If you are able to check by measurement, my cap comes out to:

1.62 in.- overall length (minus terminal wires, but including threaded head)
.78 in.- body height, (diameter)
1.377 in. - body length (just the cylinder minus threaded head)

If size is a funtion of increased uF then maybe I do have a 1+ uF cap here.
If the weather ever gets better, I will take these to my buddy across town that can get an acurrate capacitance reading off his equipment.

Thanks again for the detailed info! Merry Christmas!

Bob

gootee Did your source give a MIL-C # ?

I have a suspicion this cap maybe a GLASS DIELECTRIC

Here is the manufacturer's website:

Interestingly, they have a technical paper about polypropylene speaker crossovers:
