Well, and now we have our result:
Figure 8-14: Measurement of a 280 µH inductor with the B-WIC impedance adapter
By using the cursors we can gather the following information on the measured inductor:
• The inductor has an inductance of 280 µH up to roughly 10 kHz
• The resistance of the inductor starts around 147 mΩ and rises up to 10 Ω at 100 kHz.
• Above 10 kHz the inductance starts to drop and at roughly 2 MHz the inductor has its self-
resonance frequency. Above the self-resonance frequency, the capacitive behavior dominates.
