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
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
to +140°C with derated current
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)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
One per billion hours / one billion hours, calculated per Telcordia SR-332
Packaging A0xT: 700/7″ reel; 2500/13″ reel Plastic tape: 12 mm wide,
0.32 mm thick, 8 mm pocket spacing, 3.3 mm pocket depth

1. When ordering, please specify tolerance, termination and packaging codes:
A02TGLC
Tolerance: F=1% 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 at 150 MHz with an Agilent/HP 4286 or equivalent, 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 or equivalents.
5. SRF tested on an Agilent/HP 8720D or equivalent and a Coilcraft SMD-D fixture.
6. DCR tested on the Cambridge Technology Model Micro-ohmmeter or equivalent.
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.
