Notes

When ordering, please specify packaging code: e.g. WA8417-ALD
Inductance is for the primary, measured on an Agilent/HP 4284 at 400 kHz, 0.6 Vrms, 0 Adc.
Isat: DC current that causes an inductance drop of 30% (typ) from its value without current.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance measured between pins 3 and 4 at 400 kHz, 0.6 Vrms, 0 Adc with pins 10 and 9 shorted.
2500 Vrms, one minute isolation from primary to secondary.

Termination:

RoHS tin-silver-copper (95.5/3.8/0.7) over tin over nickel over phos bronze.

Packaging:

D = 13″ machine ready reel. EIA-481 embossed plastic tape (600 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 D.

Soldering/Washing

Moisture Sensitivity Level (MSL):

1 (unlimited floor life at <30°C / 85% relative humidity)

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.

Refer to Soldering Coilcraft Components before soldering.

PCB Washing:

Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
