2. Inductance tested at 100 kHz, 0.1 Vrms,
0 Adc using an Agilent/HP 4263B LCR
meter or equivalent.
3. DCR measured on a micro-ohmmeter and a
Coilcraft CCF858 test fixture.
4. SRF measured using an Agilent/HP 8753D
network analyzer.
5. Typical DC current at which the inductance
drops the specified amount from its value
without current.
6. Typical current that causes the specified
temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount
Components” before soldering.
