Mini Spring™ Air Core Inductors
• Small air core inductors feature high Q and tight tolerances
• Acrylic jacket provides a flat top for pick and place
• Solder coated leads ensure reliable soldering
Designer’s Kit C302 contains 12 each of all 5% values.
Kit C302-2 contains12 each of all 2% values.
Terminations RoHS compliant tin-silver over copper. Other
terminations available at additional cost.
Ambient temperature –40°C to +125°C with Irms current, +125°C

1. When ordering, please specify tolerance, termination and packaging codes:
A02TGLC
Tolerance: G = 2% J = 5% K = 10% (Table shows stock tolerances in bold.)
Termination: L = RoHS compliant tin-silver (96.5/3.5) over copper.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
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 with an Agilent/HP 4286, a Coilcraft SMD-A and correlation.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured at 150 MHz using an Agilent/HP 4291A with an Agilent/HP 16193A
test fixture.
5. SRF tested on an Agilent/HP 8720D and a Coilcraft SMD-D test fixture.
6. DCR tested on the Cambridge Technology Model 510 Micro-ohmmeter.
7. Current that causes a 15°C temperature rise from 25°C ambient.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
