Impedance Behavior

Impedance vs. Frequency (characteristic shape for 10µH ferrite inductor)

SRF: 32 MHz Inductive Capacitive Usable range (≤ SRF) 0 Ω 314 Ω 628 Ω 1.3 kΩ 2.5 kΩ |Z| impedance 1M 10M 50M 500M 1G
Impedance peaks at the self-resonant frequency (SRF). Below SRF the part behaves as an inductor; above SRF it's capacitive. Use at ≤ ⅓ SRF for predictable inductive behavior.
