When ordering, please specify termination and packaging codes: XFL4020-472MEC Termination: E = RoHS compliant tin-silver over copper. 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 (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 1 MHz, 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 25C that causes the specified inductance drop from its value without current. Click for temperature derating information. 6. Current that causes the specified temperature rise from 25C ambient. This information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information. 7. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.

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.
