High-Current Air Core Inductors Document 625-1 Document 625-1 Revised 10/13/15 SRF DCR Part Inductance2 Q2 typ3 max4 Irms5 Wt number1 ±5% (nH) typ (GHz) (mOhm) (A) (mg) GA3092-AL_ 3.7 100 17.5 2.0 7.0 150 GA3093-AL_ 6.6 100 4.0 2.0 7.0 220 GA3094-AL_ 12.0 140 2.4 2.0 7.0 280 GA3095-AL_ 17.5 140 2.2 2.0 7.0 390 1. When ordering, please specify packaging code: 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. Terminations RoHS compliant tin-silver (96.5/3.5) over copper Ambient temperature –40°C to +125°C with Irms current Maximum part temperature +140°C (ambient + temp rise) Storage temperature Component: –40°C to +140°C. Tape and reel packaging: –40°C to +80°C Resistance to soldering heat Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles Temperature Coefficient of Inductance (TCL) +5 to +70 ppm/°C 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. The use of heavy gauge wire allows these parts to have the lowest DCR and highest current ratings of our air- core inductors. They offer Q values of 100 or greater from 150 MHz to 1 GHz. Request free evaluation samples by contacting Coilcraft or visiting www.coilcraft.com.
