| Document 252-1 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.

When ordering, specify tolerance, termination and packaging codes: 1812PS-105JLC 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 40C temperature rise from 25C ambient. 9. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
