IMHO, an inductive resistor here does not matter. For one, there should
be little to no RF at this point in the circuit. Two, it's in series with
an inductor and three I think the transient response of an inductor
(initially looks like an open circuit) might actually help limit the
current even more. The third I am not sure of since it's been a while
since I've done DC transient analysis. I know on initial power up an
inductor will look like an open circuit until it is fully charged. What
about when current changes? Isn't there a response time for current to
change in an inductor? If so, in a current limiting application, an
inductive resistor would be desirable.
As for in the RF part (supressor), I feel that the resistor should have
as little L as possible.
