1812DPS Coupled Inductors for xDSL
The 1812DPS Series features a unique dual winding
configuration that provides two balanced coupled induc-
torsinasinglepackage.Thisincreasescircuitefficiency,
reducescomponentcountandconservesvaluableboard
space.
This magnetically shielded part is optimized for various
xDSL filtering applications. Its small size and low profile
makeitparticularlyattractiveforcentralofficeequipment.
These parts can be ordered with terminations that make
them compliant with RoHS standards.
In addition to the standard inductance values shown,
Coilcraft can customize these inductors to help achieve
specific corner frequencies.

1. When ordering, please specify packaging code:
181±DPS-473MC 181±DPS-473MLC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic tape (500 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 (2500 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. Average current for a 40°C rise above 25°C ambient.
6. Operating temperature range -40°C to +85°C.
7. Electrical specifications at 25°C.
See Qualification Standards section for environmental and test data.
