2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP
4263B LCR meter or equivalent.
3. SRF measured using Agilent/HP 8753D network analyzer.
4. DC current at which the inductance drops 10% (typ) from its value
without current.
5. Current that causes a 40°C temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
