1. When ordering, please specify packaging code:
0805USB-902MLC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (2000 parts per full reel). Quantities less than
full reel available: in tape (not machine ready) or
with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our
part numbering system, Coilcraft is eliminating
the need for multiple packaging codes. When
ordering, simply change the last letter of your part
number from B to C.
D
= 13″ machine-ready reel. EIA-481 embossed plastic tape (7500 parts per full reel).
2 Frequency at which the differential mode attenuation equals −3 dB
3. Inductance measured at 100 MHz using an Agilent/HP 4286A
impedance analyzer and a Coilcraft SMD-A fixture.
4. DCR is specified per winding.
5. Winding to winding isolation (hipot) tested for one minute.
6. Current per winding that causes a 20°C rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
