Packaging: C= 7″ machine-ready reel. EIA-481 embossed plastic tape (1000 parts per full reel). B= Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter C instead. D= 13″ machine-ready reel. EIA-481 embossed plastic tape (3500 parts per full reel). 2. Inductance tested at 100 kHz, 0.1 Vrms. 3. SRF >13 MHz measured using Agilent/HP 8753D network analyzer; <13 MHz using Agilent/HP 4192A. 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.
