Chip Inductors
–
1812CS Series (4532)
These parts can be ordered with Ag/Pd/Pt terminations
that make them compliant with RoHS lead free standards.
Coilcraft 1812CS ceramic chip inductors are ideal for
applications requiring mid-range inductance. The SRFs
of the parts in this series are up to 3 times higher than
those of commonly available 1812 chip inductors made
on ferrite cores.

1. When ordering, specify tolerance, termination and packaging codes:
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 8753D network analyzer and a
Coilcraft SMD-D test fixture.
6. DCR measured on a Cambridge Technology micro-ohmmeter and a
Coilcraft CCF859 test fixture.
1812CS-333XGBC
Tolerance: G = 2% J = 5% K = 10%
(Table shows stock tolerances in bold.)
Termination: B = Standard L = RoHS compliant Ag/Pd/Pt
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (600 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 (2200 parts per
full reel).
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.
See Qualification Standards section for environmental and test data.
