Document 214 -1 SMT Power Inductors - LPT1606 Series This product has been discontinued as of September 1, 2000 A recommended alternative is the DO1606 Series. Existing customers will be supported. For more information, please contact Coilcraft. The LPT1606 Power Wafer® is a very small self-shielded power inductor. Its toroid construction minimizes stray noise while its 2 mm height and tiny footprint free up board space. The 1 µH part has a saturation current rating of 3 A, remarkable for an inductor this size.

When ordering, please specify packaging code: LPT1606MLC Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic tape (2000 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 (7500 parts per full reel). 2. Inductance tested at 100 kHz, 0.1 Vrms. 3. DC current at which the inductance drops 30% (typ) from its value without current. 4. Average current for a 40°C temperature rise from 25°C ambient. 5. Operating and storage temperature range –40°C to +85°C. 6. Electrical specifications at 25°C. See Qualification Standards section for environmental and test data.
