1. When ordering, please specify packaging code:
CQ7584-ALC
Packaging: C = 7machine-ready reel. EIA-481 embossed plastic
tape (250 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 = 13machine-ready reel. EIA-481 embossed plastic
tape Factory order only, not stocked (1000 parts per
full reel).
2. Frequency at which the differential mode attenuation equals 3 dB
3. Inductance shown for each winding, measured at 10 kHz, 0.1 Vrms,
0 Adc on an Agilent/HP 4263B LCR meter or equivalent.
4. Current that causes a 40°C temperature rise from 25°C ambient. This
information is for reference only and does not represent absolute maxi-
mum ratings.
5. DCR is specified per winding.
6. Isolation (hipot) measured for two seconds.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
