Mini Spring 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
placementandrefloworvaporphaseprocessing.Solder

1. 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 15°C rise above 25°C ambient.
8. Operating temperature range -40°C to +125°C.
9. Electrical specifications at 25°C.
See Qualification Standards section for environmental and test data.
