Mystery component label 'RF'

[autopoiesis]

Curious about the ~50 components labelled RF on a crossover I'm refurbishing.

Although labelled 100PF, clearly not simply a cap (three legs and too small value!); printed markings too vague for Google.

No mention of 'RF' as a reference designator at https://en.wikipedia.org/wiki/Reference_designator; that symbol not found at CIRCUIT SYMBOLS

All are at in/outs, presumably to sink any RF to ground.

What's its proper name?

TIA,
AP

I suggest the RF prefix may be just a reference code to a parts list.
If I were to guess it could mean connecting cable with 100pf capacitance

100pF 3 terminal capacitor, bead inductors optional.

Could be a feed through capacitor to eliminate RF at input .
100pF is a common value

Insomniac Aussies to the rescue 🙂

Yup, Max/Dan - looks pretty much like that.

Thank you all!
