When ordering, please specify packaging code: 1812DPS-473MLC Packaging: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 40°C temperature rise from 25°C ambient. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
