I would say if 60 nH is accurate, that could have quite an effect on the
overall supressor design. The reason is that the supressor coil itself
is in the 60 to 100 nH range. So in effect you have 2 inductors paralled
which (for 2 60 nH Ls in parallel with no resistance in either L) would
give a total inductance of only 30 nH. Yes, there's resistance in the
second one (which makes the combination I just did invalid) so you can't
do a true parallel combination without doing some parallel/series
conversions, but having an indcutance in the resistor as large as the
supressor inductor would IMHO, make a big difference.
