Wikipedia says the self-resonance frequency (SRF) of an inductor is the point where it ceases to function as an inductor. Right now I have a 180MHz circuit, and a choice of inductors with SCFs ranging from 240MHz to 1.8GHz.
I'm guessing the 240MHz components are too close. In general, what SRF range do you shoot for if you already know your operating frequency? Two or three times higher?
