Mystery component label 'RF'

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

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