1 When ordering, please specify packaging code: e.g. JA4590-ALC
Packaging:

 

D = 13" machine-ready reel
EIA-481 embossed plastic tape 175 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 shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
3 DCR is for each winding. When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value.
4 SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value.
5 Leakage Inductance is for one winding, measured with the other winding shorted.
6 Isat: DC current, at which the inductance drops 20% (typ) from its value without current. It is the sum of the current flowing in both windings.
7 Irms, both windings: Equal current when applied to each winding simultaneously that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
8 Irms, one winding: Current when applied to one winding that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
9 Ambient temperature range: −40°C to +85°C with Irms current.
10 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
11 Maximum part temperature: +125°C (Ambient + temperature rise)
12 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.
13 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.
