Shielded Power Inductors – EPL2010 Document 584-1 Document 584-1 Revised 09/08/15 1. When ordering, please specify termination and packaging codes: EPL2010-103MLC Termination: L = RoHS compliant tin-silver-copper over tin over nickel Special order, added cost: S = non-RoHS tin-lead (63/37). Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic tape (2000 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 (7500 parts per full reel).

  • Smallest shielded power inductors; 2.0 × 2.0 × 1 mm high
  • Extremely low DCR and very high SRF ratings
  • Isat ratings as high as 2.9 A 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.
