I bought a bag of components from the bring and buy stall at Harpenden.
There were some interesting components that I have not come across before.
Here are a few.
I thought it unusual to see small diodes in a metal can, open at one end. The body is about 5mm long. I cant find any reference to the CV number, it must be highly top secret.
The black resistor is 499k (light reflection makes it look like 429) obviously 500k was not precise enough for the circuit designers, it should be useful for checking the high ranges of my DMM, and the pink resistor should be useful for checking the low ranges.
This object which looks like a multi tap power resistor has me puzzled. What is it and how do those measurements work out
I originally thought this was just a glass tube, then I noticed it does appear to have something inside it. You can just see the tiny little bead just under the second T in "Thermistor" and the almost invisible wires coming from each side of the bead. There are no external connections outside of the glass tube so I am assuming the glass tube is just protective packaging and would be broken to remove the thermistor from the inside. As a scale the glass tube is about 3mm diameter.
Oh, and these cup things which look like some sort of ceramic, what are they? They fit nicely on the tips of my fingers and are good at annoying every one if I drum my fingers on the desk.
. The writing on it looks like LECO 12 and then repeated on the other side.
