LPO4812 Series

Low Profile Surface Mount Power Inductors

RoHS compliant AEC-Q flag
Coilcraft LPO4812 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
  • AEC-Q200 Grade 3 (−40°C to +85°C)

Notes
  1. When ordering, please specify termination and packaging codes: e.g. LPO4812-224KLC
  2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter or equivalent.
  3. DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  4. Isat: DC current at 25°C that causes a 10% (typ.) inductance drop from its value without current. Temperature derating curves.
  5. 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 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (3500 parts per full reel).
  • B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
