the Callins is in an epoxy sealed container

Interesting, but it doesn't answer my question:

Why was the circuit designed to use a Callins in C7?

If it was designed to use a Callins cap, then Callins
would show up on the schematic and BOM.

As it is, specifying a 6V electrolytic to filter a
6.2V reference is probably a mistake.

Excellent observation! There's actually a 25 V Callins on the board
itself. So, there's definitely a mistake on the schematic.

Danke,
