Document 233-1 SMT Power Inductors - LPO1704 Series We now offer an improved version of this series: LPO6610. It has identical electrical specifications and footprint, and comes in a more robust package that features part identification marking. We will, however, continue to produce the LPO1704 indefinitely. Measuring just 1 mm high, the LPO1704 is the world’s lowest profile power inductor! This series has been specially designed for applications requiring the smallest possible footprint and lowest height: notebook computers, PDAs, PC Cards, mobile phones and other handheld products. 1 1 Part number1 LPO1704-122ML_ LPO1704-152ML_ LPO1704-222ML_ LPO1704-332ML_ LPO1704-472ML_ LPO1704-682ML_ LPO1704-103ML_ LPO1704-153ML_ LPO1704-223ML_ LPO1704-333ML_ 1 2 L DCR SRF ±20% max typ (µH) (Ohms) (MHz) 1.2 0.08 190 1.5 0.10 140 2.2 0.12 115 3.3 0.16 90 4.7 0.20 88 6.8 10 15 22 33 2 Isat3 3Irms4 (A) (A) 2.1 1.7 1.9 1.5 1.6 1.4 1.3 1.2 1.1 1.1 0.32 0.41 0.55 0.85 1.3 66 55 42 38 29 0.90 0.80 0.65 0.50 0.40 0.85 0.75 0.60 0.52 0.42 LPO1704-473ML_ LPO1704-683ML_ LPO1704-104ML_ LPO1704-154ML_ LPO1704-224ML_ 47 68 100 150 220 1.8 2.5 3.5 5.0 7.0 22 18 14 12 10 0.35 0.30 0.25 0.18 0.16 0.36 0.30 0.26 0.21 0.18 LPO1704-334ML_ 330 15.0 8 0.13 0.13 The specially designed ceramic case totally protects the winding while the flat top provides the best possible surface for pick and place handling. 1. When ordering, please specify packaging code: LPO1704-334MLC 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. 2. Tested at 100 kHz, 0.1 Vrms, 0 Adc. 3. DC current at which the inductance drops 10% (typ) from its value without current. 4. Average current for a 40°C rise above 25°C ambient. 5. Operating temperature range -40°C to +85°C. 6. Electrical specifications at 25°C. See Qualification Standards section for environmental and test data. Specifications subject to change without notice.
