1 When ordering, please specify packaging code: e.g. PTRF4000LD
  Packaging: C = 7" machine-ready reel
EIA RS-481 clear plastic tape (500 parts per full reel).
B = Less than full reel
In tape, not machine ready.  To have a leader and trailer added ($25 charge), use code letter C instead.
D = 13" reel, machine-ready 
EIA RS-481 clear plastic tape. Factory order only, not stocked (2000 parts per full reel).
2 Frequency at which the differential mode attenuation equals 3 dB
3 Inductance shown for each winding, measured at 130 kHz..
4 DCR is for each winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Interwinding isolation (hipot) tested for one minute.
6 Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
7 Ambient temperature range: −40°C to +85°C
8 Storage temperature range: Component: −40°C to +85°C
Tape and reel packaging: −40°C to +80°C
9 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
10 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.
