Shielded Power Inductors – XPL4020 Document 683-1 Document 683-1 Revised 10/15/09 Inductance DCR3 SRF Isat (A)5 Irms (A)6 ±20%2 (mOhms) typ4 10% 20% 20°C 40°C Part number1 (µH) typ max (MHz ) drop drop rise rise 1. When ordering, please specify packaging code: XPL4020-103MLC 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 =1 3″ 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 C432 contains 3 each of all values Terminations RoHS compliant matte tin over nickel over copper. Other terminations available at additional cost. Weight 0.16 g – 0.18 g Ambient temperature –40°C to +125°C. The part can be operated without damage as long as the part (ambient temperature plus temperature rise due to self heating) does not exceed +165°C. Storage temperature Component: –40°C to +165°C. 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 Excellent current handling, low DCR and s oft saturation makes them ideal for VRM/VRD applications Large terminations provide low resistance, excellent ther- mal management and the best possible board adhesion 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.
