1. 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. This
information is for reference only and does not represent absolute maximum ratings.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
