When ordering, please specify **packaging** code: ## **XFL4030-472MEC** **Packaging: C** = 7″ machine-ready reel. EIA-481 embossed plastic tape (500 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 (2000 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 25°C that causes the specified inductance drop from its value without current. 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. ## **Irms Testing** I rms 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. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. **US** +1-847-639-6400 sales@coilcraft.com **UK** +44-1236-730595 sales@coilcraft-europe.com **Taiwan** +886-2-2264 3646 sales@coilcraft.com.tw **China** +86-21-6218 8074 sales@coilcraft.com.cn **Singapore** + 65-6484 8412 sales@coilcraft.com.sg Document 1048-1 Revised 10/09/17 © Coilcraft Inc. 2017 This product may not be used in medical or high risk applications without prior Coilcraft approval.
