Inductance tested at 300 kHz, 0.1 Vrms on Agilent/HP 4192A. 2. DCR measured on a Keithley 580 micro-ohmmeter or equivalent. 3. SRF measured on an Agilent/HP 8753ES network analyzer. 4. DC current at which the inductance drops the specified amount from its value without current. 5. Current that causes the specified temperature rise of the winding from 25°C ambient. Temperature rise of the core is usually less than that of the winding. 6.
