Notes:
The B2005 and B2013 are common mode chokes that reduce common mode voltages in the low frequency range that may be caused by telephone ringing signals or by
interference from radio transmitters in the ADSL frequency range. The chokes are also designed to accommodate DC currents up to 100mA.

Inductors And
Common Mode Chokes
For Use in ADSL POTS Low Pass Filters
Performance Description
The series of coupled inductors shown on this data sheet are current and temperature, high self-resonant frequency, low
ideal for use in Asymmetrical Digital Subscriber Line (ADSL) applications where a low pass filter is required to separate
the voice frequencies from the data frequencies that are carried on an ADSL line. In spite of their small footprint and low
profile, these coupled inductors provide excellent electrical performance. They have stable inductance with varying DC
current and temperature, high self-resonant frequency, low coupling capacitance, and excellent balance. The common
mode chokes were developed to reduce common mode voltages in the low frequency range that is used for voice
transmission. The chokes are also designed to accommodate DC currents up to 100 mA.
Application Circuit
The following schematic depicts a typical LC filter that
incorporates the use of a common mode choke in addition
to the LC network. As shown in the frequency response
graph below, at low frequencies, the amplitude of the
output signal is roughly equal to the amplitude of the

input signal. At higher frequencies, the amplitude of the
output decreases. Thus, the network passes low frequency
voice signals with only a small degree of attenuation,
while it suppresses high frequency signals and acts as a
low pass filter.
