Document 107-1 Mini SpringTM Air Core Inductors These surface mount air core "spring" inductors provide extremely high Q over a wide frequency range. They're jacketed with a high temperature material that ensures mechanical stability and very tight tolerance. It also forms a flat top, making them suitable for automatic placement and reflow or vapor phase processing. Solder coated leads ensure reliable soldering. Coilcraft Mini SpringTM inductors are available in standard EIA tape and reel packaging: 12 mm for AxxT, and 16 mm for size BxxT parts. Coilcraft Designer's Kit C302 contains samples of all 5% inductance tolerance parts. Kits with 2% tolerance parts are also available. To order, contact Coilcraft or purchase them at http://order.coilcraft.com.

When ordering, please specify tolerance and packaging codes: A02TGLC Tolerance: G = 2% J = 5% K= 10% (Table shows stock tolerances in bold.) Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic tape, 700 (AxxT) or 500 (BxxT) 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. Factory order only, not stocked, 2500 (AxxT) or 2200 (BxxT) parts per full reel. 2. Inductance measured using Agilent/HP 4286 with Coilcraft SMD-A fixture and correlation. 3. Tolerances in bold are stocked for immediate shipment. 4. Q measured using Agilent/HP 4291A with Agilent/HP 16193A test fixture. 5. SRF tested on the Agilent/HP 8720D and the SMD-D test fixture. 6. DCR tested on the Cambridge Technology Model 510 Micro-ohmmeter. 7. Average current for a 15C rise above 25C ambient. 8. Operating temperature range -40C to +125C. 9.
