HIGH TEMPERATURE Shielded Power Inductors – XFL4020 Document 745-1 Document 745-1 Revised 07/18/12 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: XFL4020-472MEC 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). 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 C436 contains 5 each of all values Environmental RoHS compliant, halogen free Terminations RoHS compliant tin-silver over copper. Other termina- tions available at additional cost. Core material Composite Core and winding loss See www.coilcraft.com/coreloss Weight 162 – 169 mg Ambient temperature –40°C to +125°C with Irms current, +125°C to +165°C with derated current. Storage temperature Component: –40°C to +165°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 1000/7″reel; 3500/13″ reel Plastic tape: 12 mm wide, 0.23 mm thick, 8 mm pocket spacing, 2.3 mm pocket depth PCB washing Only pure water or alcohol recommended
- Exceptionally low DCR – 10.8 mOhm
- Excellent current handling capability Dimensions are in inches mm 0.157 ±0.012 4,0 ±0,3 0.157 ±0.012 4,0 ±0,3 0.083 2,10 0.128 ±0.008 3,26 ±0,20 0.032 ±0.002 0,82 ±0,05 0.062 ±0.010 1,57 ±0,25 0.038 0,98 max 0.093 2,37 0.134 3,4 Recommended Land Pattern Dash number XXX 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 components. Therefore temperature rise should be verified in application conditions.
