Identify Capacitor

[Teun]

Hi,

Can someone tell me what kind of capacitor this is? Value, voltage, type etc. Or could it be a varistor? It came from a PA speaker which now has a DC voltage over the speaker. So I thought it was a decoupling capacitor.

That looks like a PTC thermistor, aka self-resetting fuse.  If you have DC voltage across the speaker (more than a few 10s of mV), the amplifier has a failed and the PTC thermistor has hopefully (but not necessarily) protected the speaker. Do not re-connect it until you have found and fixed the fault.

Mostly like a 0.65A PPTC

Yes, it looks like a 60 VDC rated PTC Polyfuse (0.65 A?)

Is this what this is?
