) ) )
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 sec waveform, 25 times for each polarity, test connection A. 2.5 kV peak voltage, 500 A minimum peak current, 2/10 sec 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.
