Capacitor value please

:Can anyone ID the value of a capacitor with the following markings. :It looks like a ceramic. : : GAP KAP : 1-2KV : ARC : :Thank you.

Did you look at the datasheet?

Since yours is marked 1 - 2Kv ARC it seems that it is 0.75pF.

It's a specialised part.

" BCcomponents Gap-Kap capacitors provide a safe reliable discharge path for stray transient overvoltages and static voltage build-up. Combination of capacitor-spark-gap construction allows the circuit designer to specify lower voltage components and consequently lower cost, with assurance that overvoltage conditions will be prevented. "

So it's specialised. I guess that will teach me not to strip components out of other equipment!

Thanks Ross.

It's not the stripping that's the problem, it's not paying attention to what's around it.

We've seen it before, people ask about esoteric parts, parts they have because they took it out of something. But if they'd left it in until they needed it, the surrounding circuitry might help to explain it. You can find some housenumber part and never find data for it, yet on the circuit board, how it's connected is well described since the parts it needs is right there. You can either trace out the circuitry or just chop that area of the circuit board off and use it as a module. I've seen people ask about IF filters and the context of the circuit would give a general idea of it's purpose (be it wide for FM broadcast, narrow and relatively low frequency for AM broadcast, really wide for TV, and so on) and the needed terminating values on the input and output would come from the resistors attached to the filter on the circuit board. But remove the filter, and that information is lost unless someone traces it at the time and records it and keeps that information with the actual part.

Not neccessarily. If you have an application for an arc suppressor, in the future, then you've got one, and the start of the basic knowledge, now, to recognize the situation and to possibly use the one you've got.

Mind you, these do have a limited application life ie number of arcing events and must be kept scrupulously clean, to continue to function as intended. Something to keep in mind.
