I'll start with saying that what I know about electronics components would not fill a paragraph.
I got a large box of Mallory pieces and I've done googl searches on the numbers to try to figure out what they are, but I don't know what to call them to even do a good search. I've determined that many of them are disc capacitors.
So, I'm wondering if some kind soul would tell me a bit about these, like what they are called and the basic area of electronics they are used for, so that I can go and do some more searching that will help me identify them more accurately.
I've never posted a picture here (I'm really not an idiot, just out of my element ). Here's a try with one, and if it works, I'll post a pic of examples of the other things in the box.
Oh my god! seems like a museum. Since awhile i didn't see some of those capacitor. I can't believe they're going to work after all these years...
Sorry but, you should trash them... or open a museum
POST#3: yup it's a capacitor. you read the color from the top to the bottom. It use the same chart as the resistor. The first 3 color are the value, the 2 last the tolerance.
Sorry for taking so long to reply. I couldn't figure out how to get back to this thread.
Thanks so much for all of the suggestions! You've been so helpful.
A friend bought a lighting business and there were boxes and boxes of electronic parts filling the shop there. I have no idea why, but I grabbed a box when he offered. They've been tucked away for about 2 years now and I came across them again the other day.
Everything except the purple electrolytic is probably fine. That electrolytic may have dried up, and no longer be useable. The rest are actually prety high quality parts from respected makers, Cornel Dublier, etc.
Mike, I think the left cap in post 1 is a 10uF tantalum. Look closely - I think it reads 106K (10uF), not 104K (0.1uF). I don't know what the shelf life is, but I haven't seen tantalums like that in about 30 years. They may not be that old, though.
Some Mil spec parts are still made "old school" and look like that. but from the rest of the collection I wouldn't be suprised if the lot is 30 years old.
Tantalum caps, if they don't get wet inside, generally last many many many years. There is a ton of telephone equipment out there with those types of tant's inside, doing yeoman's duty 24/7.
Yep, you are right, I clicked the picture.. 106K for sure.. They look like the .1uF and .01uF I have, same can and everything. I had no idea they were tantalums (so used to seeing the dipped ones). I picked up a few bags of them probably 15+ years ago and still have a lot of them.
But they seem to work fine. Guess I better check the shelf..
