When ordering, please specify packaging code: 13 machine-ready reel. EIA-481 embossed plastic tape. Factory SD54-224KLC order only, not stocked (3500 parts Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic tape (400 parts per full reel). 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. Factory order only, not stocked (1500 parts per full reel). 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4284A impedance analyzer or equivalent. 3. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD -D test fixture. 4. DC current at which the inductance drops the specified amount from its value without current. 5. Current that causes the specified rise from 25C ambient. 6. Electrical specifications at 25C. Refer to Doc 362 Soldering Surface Mount Components before soldering.
