MLC1770 Series

Shielded Power Inductors

符合RoHS 无卤素
Coilcraft MLC1770 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)

注释
  1. When ordering, please specify termination and packaging code: e.g. MLC1770-282MEC
  2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD‑A fixture in an Agilent/HP 4263B LCR meter.
  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/HP4291A impedance analyzer and an Agilent/HP 16193 fixture.
  5. Isat: DC current at which the inductance drops the specified amount from its value without current. Details
  6. Irms: Current that causes the specified temperature rise from 25°C ambient.

端子:

  • E = Halogen free component. RoHS compliant tin-silver over copper 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)

包装:

  • D = 13" machine-ready reel
    EIA-481 embossed plastic tape (400 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 D instead.
