Power Chip Inductors – 1812PS Series
• Economical alternative to larger shielded power inductors.
• Ferrite cover provides magnetic shielding
For new designs, we recommend the LPS4018 or
LPS5030 as an alternative to this series. They offer
better current handling, lower DCR, a lower profile and
a smaller footprint. We will continue to manufacture
and support the 1812PS.

1. When ordering, specify tolerance, termination and packaging codes:
1812PS-105JLC
Tolerance: J = 5% K = 10%
(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 (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).
2. Inductance measured at 100 kHz, 0.1 Vrms, using aCoilcraft SMD-A
fixture in an Agilent/HP 4263B LCR meter.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured at 1 MHz on an Agilent/HP 4291 with an Agilent/HP 16193
test fixture.
5. DCR measured on micro-ohmmeter and a Coilcraft CCF840 test fixture.
6. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
7. DC current at which the inductance drops 10% (typ) from its value
without current.
8. Current that causes a 40°C temperature rise from 25°C ambient.
9. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
