1 When ordering, please specify packaging code: e.g. RA7231-ALD
Packaging: D = 13" reel, machine-ready 
EIA-481 embossed plastic tape (150 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 each winding, measured at 100 kHz, 1.0 Vrms, 0 Adc using an Agilent/HP 4284A impedance analyzer.
3 DCR is for each winding, measured on a micro-ohmmeter at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 SRF measured using Agilent/HP 8753D network analyzer.
5 Isat: DC current (typical) at which the inductance drops the specified amount from its value without current.
6 Irms: Current applied to both windings at the same time that causes the specified temperature rise from 25°C ambient.
7 Ambient temperature range: −40°C to +125°C with (40°C rise) Irms
8 Storage temperature range: Component: −40°C to +165°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +165°C (Ambient + temperature rise)
10 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.
11 Electrical specifications at 25°C.
