Mini Spring™ Air Core Inductors - Coilcraft - #1

Document 107-1

• 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

When ordering, please specify tolerance, termination and packaging codes:

1.

135°. max

-1 1 JT

G =2% J = 5% K = 10% (Table shows stock tolerances in bold.) 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).

0° min

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.

See Qualification Standards section for environmental and test data. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
