What value af cap's ???

[ksor]

I got a nice box with lots of capacitor, sorted out in different small rooms in the box.

Unfortunately there is no sign telling the value af each cap.

They are so small I nearly can't read the letters and digits on the caps - but with a magnifying glass it can be done.

But what I see don't tell ME much more af the value - what does "1M" mean or "0,01Z 100V" ...

Do you have a link to a site where I can see how these values should be interpreted ?

I would think that 1M = 1 million PF = 1 uF
and 0,01 Z could be 10.000 pF = 10 nF.
But the best way is to measure them, or compare the values with a well known capacitor.

the 100V would probably be the Power/Voltage Rating...
as in.. don't use in appliances that rock over 100V...

Yeah, but there is a lot of other "codes" I have to decipher.

Meassure each of them ... argh, but I'm too stingy to just through them away !

Maybe this could be a project in the  future - but right now I'm in the middle of another one - so it'll have to wait !

Why not buy an LCR meter..............best buy i ever made !

Here is an easy way to measure capacitors if you only have a tone generator and a millivoltmeter. (Or a device with a VU meter in it...)

1. Connect the output of the tonegenerator to the input of the meter through the capacitor you want to test.
2. Connect a resistor of 10 K in parallel with the input of the meter.
3. Set the generator to 20 KHz and adjust the level for 1 Volt or 0 VU.
4. Lower the frequency, so that the measured level drops 6 dB.
5. Substitute the unknown capacitor by a known value that gives the same meter indication.
In this case you know the value of the measured capacitor!

This will not work for very small (pF) or big (uF) values.

Yeah, but I suspects the value of these caps to be very, very small - for sure pF's !

They are not SMD, but physically very small anyway - 1.5 X 2 mm I think - so they are for sure not uF 

I found out some of then are Tantals - light brown drop-shape - and in fact the value and polarity is printed on them with very, very small letters
