Analog electronics are annoying
Resistors are resistors. They retain their resistance across basically all frequency, current, and temperature ranges, up until the point where the current is too high (at which point the resistance goes to infinity, permanently).
Capacitors retain their capacitance across a wide range of frequencies and current (which isn't to say that the effects aren't dependent on frequency, merely that the capacitance value doesn't change). However, the capacitance changes considerably with temperature change.
Inductors retain reasonably constant inductance over temperature variations. However, the inductance varies widely (and non-linearly, so far as I can tell) with frequency and current variations.
I am finding the latter 2 somewhat vexing at the moment.
