Rick, in my previous existence with a filter manufacturer, I was not aware of any filtered DIN style connectors, and I'm not sure the connector construction would allow easy grounding of a planar style capacitor array. The initial obvious suggestion is, have you considered a ferrite bead placed over all three leads? The advantage of the ferrite is that it will absorb some of the rf energy, rather than recirculate it to a ground plane, as with a capacitor filter.
