1 When ordering, please specify packaging code: e.g. PFD3215-103MEC
Packaging:

 

C = 7" machine-ready reel
EIA-481 embossed plastic tape 2000 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 = 13" machine-ready reel
EIA-481 embossed plastic tape. Factory order only, not stocked (3500 parts per full reel).
2 Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent.
3 DCR is for each winding.  DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Ambient temperature range: −40°C to +85°
5 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
6 Maximum part temperature: +125°C (Ambient + temperature rise)
7 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.
8 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.
