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

" 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. "

Did you look at the datasheet?

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

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.

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