Document 433-1 SMT Power Inductors - LPS4012 Series This LPS4012 series of low profile shielded power inductors is designed with PDAs, wireless phones, digital cameras and other handheld products in mind. These inductors have exceptionally low DCR and exceptional current handling capability for parts this size. They are available in 27 values from 0.28 H to 3.3 mH. The specially designed cover completely protects the windings and provides the best possible surface for pick and place handling. Parts shown in bold are stocked for immediate delivery. Other parts are special order. For free evaluation samples, contact Coilcraft or order them online at www.coilcraft.com.

When ordering, please specify tolerance and packaging codes: 2. 3. 4. 5. 6. 7. 8. LPS4012-682MLC Tolerance: M = 20% N = 30% (Table shows stock tolerances in bold.) Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic tape (1000 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 (3500 parts per full reel). Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc. Tolerances in bold are stocked for immediate shipment. DCR measured on a micro-ohmmeter. SRF measured using Agilent/HP 8753ES or equivalent. For inductance values 10 H, DC current at which the inductance drops 20% (max) from its value without current. For inductance values <10 H, DC current at which the inductance drops 30% (max) from its value without current. Storage and operating temperature range -40C to +85C. Electrical specifications at 25C.
