The 1812DPS Series features a unique dual winding
configuration that provides two balanced coupled induc-
tors in a single package. This increases circuit efficiency,
reduces component count and conserves valuable board
space.
This magnetically shielded part is optimized for various
xDSL filtering applications. Its small size and low profile
make it particularly attractive for central office equipment.
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:
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
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.
