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.

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.
