LPO3310 Series

Low Profile Surface Mount Power Inductors

RoHS compliant
Coilcraft LPO3310 Series low-profile, unshielded surface-mount power inductors offer low DC resistance and high saturation current ratings in a compact package. The low-profile ceramic case provides thermal stability and an excellent surface for pick-and-place handling.
  • Low profile for compact packaging
  • High saturation current ratings
  • Ceramic case for thermal stability
  • Ferrite core for flat L vs I curve

Notes
  1. When ordering, please specify termination and packaging codes: e.g. LPO3310-473MLC
  2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4192A.
  3. DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  4. SRF measured using an Agilent/HP 8753ES or equivalent.
  5. Isat: DC current at 25°C that causes a 10% (typ.) inductance drop from its value without current. Temperature derating curves.
  6. Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

Termination:

  • L = Silver-palladium-platinum-glass frit terminations.
  • T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
  • S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape (1000 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 per full reel)
