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.
