Impedance Behavior

Impedance vs. Frequency (characteristic shape for 470nH ferrite inductor)

SRF: 100 MHz Inductive Capacitive Usable range (≤ SRF) 0 Ω 30 Ω 75 Ω 150 Ω 240 Ω 600 Ω |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.
