At the moment they have only 2 cores available in stock and it might take weeks to get more. Baluns can get away with using high loss core material like Type 43 (which in non-isolated transformers like this is actually preferable) because the bifilar winding and roughly balanced current passing through the two windings ensures that the core should only be carrying the common mode current, which is some small fraction of the total, and which you want to attenuate (that's choking impedance). 30mm, id 1.
