1008LSSeries(2520)
These ferrite core surface mount inductors have lower
DCR and higher current ratings than our 1008CS Series.
They’re available with inductance values from 1.2 to 10 µH.
Coilcraft
Designer’s Kit C136
contains samples of all
5% inductance tolerance parts. To order, contact Coil-

K
= 10%
(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-481 embossed 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.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured using Agilent/HP 4291A with Agilent/HP 16193 test fixture.
5. SRF measured using Agilent/HP 8753D network analyzer with Coilcraft
SMD-D fixture.
6. DCR measured on Cambridge Technology Micro-ohmmeter.
7. Average current for 15°C temperature rise from 25°C.
8. Operating temperature range
−40°C
to +85°C.
9. Electrical specifications at 25°C.
