Chip Inductors–1812CS Series (4532)
Document 105-1
Specifications subject to change without notice.
Document 105-1
Revised 11/13/03
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.
These parts can be ordered with Ag/Pd/Pt terminations
that make them compliant with RoHS lead free standards.

See Qualification Standards section for environmental and test data.
For part marking data see Color Coding section.
1. When ordering, specify tolerance, termination and packaging codes:
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).
