When ordering, please specify packaging code: 1812DPS-473MLC C = 7 machine-ready reel. EIA-481 embossed plastic tape (600 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 (2200 parts per full reel). 2. Per winding. Tested at 100 kHz, 0.1 Vrms, 0 Adc. 3. Q measured at 1 MHz. 4. DC current at which the inductance drops 10% (typ) from its value without current. 5. Current that causes a 40C temperature rise from 25C ambient. This information is for reference only and does not represent absolute maximum ratings. 6. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
