A practical deep-dive into inductor hardware design covering non-ideal parameters beyond basic inductance: DC resistance, self-resonant frequency, saturation behavior, core materials, and derating effects. Demonstrates how to measure impedance vs. frequency using a Bode 100 vector network analyzer with a two-port shunt setup, extract equivalent circuit model parameters (series resistance, parallel winding capacitance, parallel resistance), and simulate them in LT Spice. Includes comparison of ideal vs. non-ideal inductor models in low-pass filter simulations, and closes with practical part selection guidelines for RF, power, and audio applications.
