In Reply to: resistor-capacitor to cut high frequency, but why no inductors? posted by dave789 on January 18, 2009 at 12:12:49:
Inductors also have a tendency to pick up AC hum unless made certain ways or shielded.
Inductors are relatively poorly behaved components compared to resistors and capacitors, too. Resistors and capacitors at audio frequency act pretty close to ideal mathematical resistors and capacitors (nearly entirely resistance or capacitance), but real-world inductors show resistive and capacitive behavior along with only so-so inductance. They also often have to be made with magnetic cores that can saturate or act nonlinearly. All of which can make them do non-ideal things like give resonances or other odd frequency effects or cause distortions.
Maybe if physicists ever get room temperature superconductors going, inductors might get more generally usable!
