When ordering, please specify packaging code: 0805USB-902MLC Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic tape (2000 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 (7500 parts per full reel). 2 Frequency at which the differential mode attenuation equals -3 dB 3. Inductance measured at 100 MHz using an Agilent/HP 4286A impedance analyzer and a Coilcraft SMD-A fixture. 4. DCR is specified per winding. 5. Winding to winding isolation (hipot) tested for one minute. 6. Current per winding that causes a 20C rise from 25C ambient. 7. Electrical specifications at 25C.
