1 When ordering, please specify packaging codes: e.g. DFT7160-475BLC
  Packaging: C = 7" reel, machine-ready 
EIA-481 embossed plastic tape (250 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 D instead.
D = 13" reel, machine-ready 
EIA-481 embossed plastic tape. Factory order only, not stocked (1000 per full reel).
2 Frequency at which the differential mode attenuation equals 3 dB
3 Inductance measured at test frequency using an Agilent/HP 4286A impedance analyzer and a Coilcraft SMD-A fixture
4 Irms: Current that causes a 20°C temperature rise from 25°C ambient.
5 DCR is specified per winding at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
6 Ambient temperature range: −40°C to +85°C
7 Storage temperature range: Component: −40°C to +105°C
Packaging trays or tubes: −40°C to +80°C
8 Maximum part temperature: +125°C (ambient + temp rise);
9 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
