1. Inductance measured at 100 kHz, 1.1 Vrms, 0 Adc using an Agilent/
HP 4263B impedance analyzer or equivalent.
2. SRF tested on an Agilent/HP 4192A.
3. DC current at which the inductance drops the specified amount from its
value without current.
4. Current that causes the specified temperature rise from 25°C ambient.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
