1. When ordering, please specify packaging code:
1812DPS-473MLC
C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (600 parts per full reel). Quantities less thanfull reel available: in tape (not machine ready) orwith leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor multiple packaging codes. When ordering, simply
change the last letter of your part number from B to D.
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.
