When ordering, please specify packaging code: EPL3314-473MLC Packaging:C=7″ machine-ready reel. EIA-481 embossed plastic tape (2000 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 (7500 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 network analyzer or equivalent. 5. DC current at 25°C 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 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
