High-Current Air Core Inductors
The use of heavy gauge wire allows these parts to have
the lowest DCR and highest current ratings of our aircore inductors. They offer Q values of 100 or greater from
150 MHz to 1 GHz.

1. When ordering, please specify packaging code:
Temperature Coefficient of Inductance (TCL) +5 to +70 ppm/°C
GA3095-ALC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (250 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 C instead.
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (1000 parts per full reel). Factory order only,
not stocked.
2. L and Q measured at 150 MHz, 0.1 Vrms, 0 A using an Agilent/HP
4291A impedance analyzer with an Agilent/HP 16193A test fixture.
3. SRF measured using an Agilent/HP 8722ES network analyzer and a
Coilcraft SMD-D test fixture.
4. DCR measured using a micro-ohmmeter.
5. Current that causes a 15°C temperature rise from 25°C ambient. This
information is for reference only and does not represent absolute
maximum ratings.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Mean Time Between Failures (MTBF) 1 billion hours
Packaging 250/7″reel; 1000/13″ reel Plastic tape: 16 mm wide,
0.35 mm thick, 12 mm pocket spacing, 4.9 mm pocket depth
PCB washing Tested to MIL-STD-202 Method 215 plus an additional
aqueous wash. See Doc787_PCB_Washing.pdf.
