MLC12xx Series

Shielded Power Inductors

RoHS compliant AEC-Q flag
Coilcraft MLC12xx Series power inductors are mechanically rugged and magnetically shielded for use in high-density circuits. Their flat-wire construction provides excellent current handling and exceptionally low DCR, and soft saturation makes them perfect for VRM/VRD applications. 
  • Exceptionally low DC resistance
  • Soft saturation for high peak current handling
  • Magnetic shielding for high-density packaging
  • Ideal for low-voltage, high-current DC-DC converters and VRD/VRM controllers
  • AEC-Q200 Grade 3 (−40°C to +85°C)

Notes
  1. When ordering, please specify termination and packaging codes: e.g. MLC1265-361MLC
  2. Inductance measured at 100 kHz, 0.1 Vrms, using a Coilcraft SMD-A fixture in an Agilent/HP 4263B LCR meter or equivalent.
  3. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. SRF measured using an Agilent/HP4291A impedance analyzer and a Coilcraft 16193 fixture. Details
  5. Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
  6. Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

Termination:

  • L = RoHS compliant tin-silver (96.5/3.5) over copper.
  • E = Halogen free component. RoHS compliant tin-silver over copper.
  • 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
  • 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.
