Notes

When ordering, please specify termination and packaging codes: e.g. GA3252-ALD
Inductance measured at 100 kHz, 0.1 V, 0 Adc using an Agilent/HP 4192A impedance analyzer or equivalent.
DCR measured on Keithley 580 micro-ohmmeter or equivalent
SRF measured on an Agilent/HP 8753ES network analyzer
Isat: DC current at 25°C that causes the specified inductance drop from its value without current
Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings

Termination:

L = RoHS compliant tin-silver (96.5/3.5) over copper.
T = RoHS tin-silver-copper (95.5/4/0.5) over copper. (Special order, added cost)
S = non-RoHS tin-lead (63/37) over copper. (Special order, added cost)

Packaging:

D = 13" reel, machine-ready
EIA-481 embossed plastic tape (200 per full reel).
B = Less than full reel
On tape not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead.
