2. Inductance tested at 100 kHz, 0.1 Vrms using an
Agilent/HP 4192A. Inductance at 1 MHz is the same
for parts with SRF ≥10 MHz.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using Agilent/HP 8753ES or equivalent.
5. DC current at 25°C that causes the specified induc-
tance drop from its value without current.
Click for temperature derating information.
6. Current that causes the specified temperature rise from
25°C ambient.This information is for reference only and
does not represent absolute maximum ratings.
