1 When ordering, please specify packaging code: e.g. WA8417-ALD
  Packaging: D = 13" machine-ready reel
EIA 481 embossed plastic tape (600 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 D instead.
2 Inductance is for the primary, measured on an Agilent/HP 4284 at 400 kHz, 0.6 Vrms, 0 Adc.
3 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Leakage inductance measured between pins 3 and 4 at 400 kHz, 0.6 Vrms, 0 Adc with pins 10 and 9 shorted.
5 Isat: DC current that causes an inductance drop of 30% (typ) from its value without current.
6 Ambient temperature range: −40°C to +125°C
7 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
8 Maximum part temperature: +165°C (Ambient + temperature rise)
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.
