  • Shielded power chip inductors  Excellent current handling for a part this size 1. When ordering, specify termination and packaging codes: 1008PS-105KLC 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 (750 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=1 3″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2500 parts per full reel). 2. Inductance measured at 100 kHz, 0.1 Vrms, using Coilcraft SMD-A fixture in Agilent/HP 4263B impedance analyzer or equivalent. 3. Q measured at 1 MHz using an Agilent/HP 16193 test fixture and an Agilent/HP 4291 or equivalent. 4. DCR measured on micro-ohmmeter and Coilcraft CCF840 test fixture. 5. SRF measured using a Coilcraft SMD-D test fixture and an Agilent/HP 8753D network analyzer or equivalent. 6. DC current at which the inductance drops the specicfied amount from its value without current. 7. Current that causes the specified temperature rise from 25°C ambient. 8. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. For new designs, we recommend the LPS4018 as an alternative to this series. The LPS4018 series offers a significantly lower profile and much lower DCR. We will continue to manufacture and support the 1008PS.
