ceramic ID

[drtyTshrt]

Please point me in a direction to learn about ceramics and compasitors and such. The photo provided is of something that came out of an amplifier. I apologize in advance for being vague. I have just been realizing that I may be passing up P Ms. This thing has some clay like insulation between the ceramics like the one shown at the top of the picture.

Not insulation but more likely a form of heat sink material to help cool the chips more efficiently. The whole thing is obviously some sort of multi-chip module. A hybrid amplifier I'd guess?

It is from an ALTO name brand. This one is from an aviation A/V system. I just want to learn more about what I may be throwing away. Any tips or insight will be Thankfull.

What you have is a DC-DC Converter, common in aviation equipment. Vicor is one maker - I haven't opened up one in a long time, but the last few I did open had no PMs present - although yours looks like it has some small monolithic caps that might yield some Pd.

Do a google image search for Vicor and you'll see.

Cheers,
Brian

i have two of those very similar in design that came out of one unit of test equipment. Mine has the pinkish play do puddy in it, not the gray. Mine looks like it will test for PM's but not one hundred percent sure yet, still waiting for my test kit.
