Chip Inductor – 1008HT Series (2520)
• Low-profile inductors are 60% the height of our other 1008
size parts.
• They feature high SRFs and very high Q factors.

1. When ordering, specify
tolerance, termination
and
packaging
codes:
1008HT-R56TJLC
F
= 1%
G
= 2%
J
= 5%
(Table shows stock tolerances in bold.)
Termination: L
= RoHS compliant silver-palladium-platinum-glass frit.
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 (2000 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 (7500 parts per full reel).
Tolerance:
2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/
HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test
fixture.
5. SRF measured using an Agilent/HP 8720D network analyzer and a
Coilcraft SMD-D test fixture.
6. DCR measured on a Cambridge Technology micro-ohmmeter and a
Coilcraft CCF840 test fixture.
7. Current that causes a 15°C temperature rise from 25°C ambient.
8. Electrical specifications at 25°C.
See Color Coding section for part marking data.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
