I have a device I am trying to repair and have discovered that three of the capacitors (2 electrolytic and 1 ceramic) have burned out.
The resistance across each electrolytic is 2.8 - 3 meg ohm (out of circuit) and the ceramic is 80 ohm (in circuit).
I have been able to order replacement electrolytics as the value was written on them, the problem is the smt ceramic cap has nothing written on it, so I don't know what to replace it with.
It is part of a power supply circuit which has five identical sections (two electrolytics and a ceramic in parallel, followed by an inductor), so I could remove one of the working ceramics from the neighbouring circuits and test it, but I don't have a capacitor tester.
Is there another way I can test the value of one of the working caps?
