2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an
Agilent/HP 4192A impedance analyzer or equivalent.
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.
