They typically have low inductance (10 nanohenry) and low electrical resistance when switched on (10-30 milliohms).
A high density gas increases the breakdown field, thus shorter arcs can be used with lower inductance and the capacity between the electrodes is increased.
A wide streamer has a lower inductance.
It makes sense, however, since class 2 capacitors are much smaller than class 1, so they ought to have lower parasitic inductance.
Chokes for even higher frequencies have non-magnetic cores and low inductance.
The lack of a core means very low inductance.
This results in a lower inductance and capacitance, and therefore lower power requirements.
Ceramic plate capacitors are usually favoured due to extremely low inductance and low cost.
Disc and plate ceramic capacitors are used due to particularly low inductance.
To obtain high torque at high speeds requires a large drive voltage with a low resistance and low inductance.
