Quick Capacitor question
 

Hi all,
I have two identical circuits - both dead, so I started checking one and
after going through bunch of dead parts (it's power amp) - dead HexFET, dead
inverter circuit I hit some capacitor that shows resistance of 3-4 Ohms both
ways (I don't have cap meter). Anyway, here is what's written on this cap
(it's a cap for sure - marked C5 and has +/- on it):
1st board:
106M 10K - this K has small horizontal lines above and below the letter)
0126
2nd:
106M 10K (same K) 0234

According to the table that I have found it is 10*10^6 +/- 20% pF, so it is
10uF +/- 20%.
Please let me know if this is correct :(

Thanks!

One more question..
How would you determine voltage rating of the capacitor if it's not written
on the cap?

What is the supply voltage in the circuit? Could the capacitor be 10 volts?

A 10 uF capacitor with no voltage marked is unusual.

Voltage rating of a capacitor does not affect the properties of the circuit
unless it is undervolted. You can always use a higher voltage rating than in
the original circuit for capacitors.

The printing sometimes wears off of components and it is no longer visible,
or it may not have been on their if some other marking from the manufacturer
identifies the capacitor.

I would wander around www.digikey.com (download the capacitor section of
their parts catalog) and look at the different sizes, types, and
manufacturer ids.

Thank you all for your suggestions.
I looked at the circuit - it has +6, +15 and +/- 80V power lines attached to
it.
The capacitor's (+ means that it is an electrolytic cap, right?) positive
terminal is attached to source of one mosfet and drain of another mosfet -
both of those FETs (IRL640) are powered by 80V power supplies.

Its negative end is attached via 3.5k resistor to collector of small BJT
transistor (MPSA42).

What kind of conclusion can I draw from this regarding capacitor's
appropriate voltage?
I went to local component store and *sizewise* 10uF 16V and 25V caps are
quite similar to this one (well, my cap is axial, but no local stores carry
axial caps, so I was looking at ones that have 2 legs at the bottom). 10uF
100V are massive compared to mine :(

I thought there was a new type of capacitor called " Quick Capacitor"
