Shielded Power Inductors – XFL4012 Document 935-1 Document 935-1 Revised 07/25/12 Inductance2 DCR (mOhms)3 SRF typ4 Isat (A)5 Irms (A)6 Part number1 ±20% (µH) typ max (MHz) 10% drop 20% drop 30% drop 20°C rise 40°C rise 1. When ordering, please specify packaging code: XFL4012-601MEC Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic tape (1500 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 (5000 parts per full reel). 2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc. 3. DCR measured on a micro-ohmmeter. 4. SRF measured using Agilent/HP 4395A or equivalent. 5. DC current at which the inductance drops the specified amount from its value without current. 6. Current that causes the specified temperature rise from 25°C ambient. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. Designer’s Kit C455 contains 5 of each XFL4012 and XFL4015 value. Core material Composite Weight 85 – 95 mg Environmental RoHS compliant, halogen free Terminations RoHS compliant tin-silver (96.5/3.5) over copper. Other terminations available at additional cost. Ambient temperature –40°C to +125°C with Irms current, +125°C to +165°C with derated current. Storage temperature Component: –40°C to +125°C. Tape and reel packaging: –40°C to +80°C Resistance to soldering heat Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C / 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 1500/7″reel; 5000/13″ reel Plastic tape: 12 mm wide, 0.23 mm thick, 8 mm pocket spacing, 1.40 mm pocket depth PCB washing Only pure water or alcohol recommended
- High current ratings and low DCR
- Very low profile, only 1.2 mm high Irms Testing Irms testing was performed on 0.75 inch wide × 0.25 inch thick copper traces in still air. Temperature rise is highly dependent on many factors including pcb land pattern, trace size, and proximity to other com- ponents. Therefore temperature rise should be verified in appli- cation conditions.
