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.
To request free evaluation samples, contact Coilcraft or

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.
