• Acrylic jacket provides a flat top for pick and place
• Solder coated leads ensure reliable soldering
Terminations
RoHS compliant tin-silver over copper. Other termina-
tions available at additional cost.

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.
