(Table shows stock tolerances in bold.)
Termination: B
= Ag/Pd/Pt/Pb
L
= Lead free Ag/Pd/Pt
Packaging: C
= 7″ machine-ready reel. EIA-481 embossed plastic tape
(2000 per full reel).
B
= Less than full reel. On 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 RS-481 clear plastic tape.
Factory order only, not stocked (7500 per full reel).
Tolerance:
2. Inductance measured using Coilcraft SMD-A fixture in Agilent/HP 4286A
impedance analyzer with Coilcraft-provided correlation pieces. For
recommended test procedures, contact Coilcraft.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured using Agilent/HP 4291A with Agilent/HP 16193 test fixture
and on Agilent/HP 8753D with Coilcraft SMD-D test fixture.
5. SRF measured using Agilent/HP 8720D network analyzer and Coilcraft
SMD-D test fixture.
6. DCR measured on Cambridge Technology micro-ohmmeter and Coilcraft
CCF840 test fixture.
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.
