| Document 248-1 1812DPS Coupled Inductors for xDSL * Coupled inductor optimized for xDSL filtering applications * Can be used as a common mode choke, 1:1 transformer or in SEPIC applications Core material Ferrite Terminations RoHS compliant gold over nickel over moly-manganese. Other terminations available at additional cost. Weight 0.30 - 0.36 g Ambient temperature -40C to +85C with Irms current, +85C to +125C with derated current Storage temperature Component: -40C to +125C. Packaging: -40C to +80C Resistance to soldering heat Max three 40 second reflows at +260C, parts cooled to room temperature between cycles Temperature Coefficient of Inductance (TCL) +200 to +700 ppm/C Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / 85% relative humidity) Failures in Time (FIT) / Mean Time Between Failures (MTBF) 38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332 Packaging 500/7reel; 2000/13 reel Plastic tape: 12 mm wide, 0.25 mm thick, 8 mm pocket spacing, 3.9 mm pocket depth PCB washing Only pure water or alcohol recommended Part number1 1812DPS-102ML_ 1812DPS-222ML_ 1812DPS-472ML_ 1812DPS-103ML_ 1812DPS-153ML_ 1812DPS-223ML_ 1812DPS-393ML_ 1812DPS-473ML_ L DCR SRF 20%2 Q max min Isat4 Irms5 (H) min3 (Ohms) (MHz) (mA) (mA) 1.0 2.2 4.7 10 15 22 39 47 38 29 43 35 37 38 39 40 0.20 0.33 0.41 0.74 0.96 1.84 2.60 2.66 285 175 102 74 65 54 5.7 4.8 2400 1500 1500 800 700 500 450 400 2100 1200 1000 780 710 530 420 390 1. When ordering, please specify termination and packaging codes: 1812DPS-473MLC Termination: L = Silver-palladium-platinum-glass frit terminations 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 (2200 parts per full reel). 2. Per winding. Tested at 100 kHz, 0.1 Vrms, 0 Adc. 3. Q measured at 1 MHz. 4. DC current at which the inductance drops 10% (typ) from its value without current. 5. Current that causes a 40C temperature rise from 25C ambient. 6. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
