COMMON MODE CHOKE
)
)
)
The application of the Common Mode Choke is EMI suppression in ISDN U-interface.
withstands power induction as specified in Figure 4 and Figure A.4 of ITU-T K.20.
The CMC is tested with pin 1 of the CMC as point A in the figures, and pin 5 as point B.
Pins 6 and 10 of the CMC are connected to the earth.
Withstands power contact as specified in Figures 5 of ITU-T K.20. The CMC is tested with
pin 1 of the CMC as point A in the figure, and pin 5 as point B. Pins 6 and 10 of the CMC
are connected to the earth.
Withstands surges as specified in The Bellcore TR-NWT001089 standard (items 6 and 10
of the table 4-2):
1 kV peak voltage, 100 A minimum peak current, 10/100
µsec
waveform, 25 times for
each polarity, test connection A.
2.5 kV peak voltage, 500 A minimum peak current, 2/10
µsec
waveform, 10 times for
each polarity, test connection B.
The CMC is tested with pin 1 of the CMC as Tip in the figure, and pin 5 as Ring. Pins 6
and 10 of the CMC are connected to the earth.
Passes 80 kbaud 2B1Q signals (differential) specified in ITU-T G.961.
