So if I had a 1kHz RC filter, do you think I could use a chip wirewound resistor? 1kHz is pretty low and if anything I *think* the inductance *might* somehow help the filtering. At the very least I don't think it would have any negative impact.

I fear the chip wire wound resistors are wound in a fasion the inductance is cancelled -- Halve the wire length by folding back at the centre - after winding the doule wire- solder the leads
instead you can staight go for chip inductors and call it LC filter

If this is a low pass with the L in series with the R, it will help roll off the response. However, if The ratio of L/R is much smaller than R*C then, your little bit of "L" is really not doing much. I imagine that the parasitic L of a wirewound chip resistor is relatively small.
I've seen some huge wire wound reostats wound on iron formers that are so inductive that they draw a huge arc from a 24V supply when they are disconnected.
