1. Inductance measured at 1 kHz, 0.1 Vrms, 0 Adc using an Agilent/
HP 4192A impedance analyzer.
2. SRF measured on an Agilent/HP 8753D network analyzer.
3. DC current at which the inductance drops 10% (typ) from its value with-
out current.
4. Current that causes a 40°C rise from 25°C ambient.
5. Electrical specifications at 25°C.
