MVR Series

VRM/VRD Power Inductors

符合RoHS AEC-Q flag

Coilcraft low-profile MVR Series shielded power inductors are great for high current DC-DC converters and VRM/VRD controllers. High-temperature, low-loss materials do not exhibit thermal aging.

  • Very low DCR and high current handling
  • Low loss and soft saturation versions
  • Low profile with excellent performance-to-height ratio
  • Magnetic shielding allows high-density packaging
  • Designed for high-current DC-DC and VRM/VRD controllers
  • No thermal aging

注释
  1. When ordering, please specify termination and packaging codes: e.g. MVR1278C-232MLC
  2. Inductance measured at 500 kHz, 0.1 Vrms using an Agilent/HP 4284A 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. SRF measured on an Agilent/HP 8753ES
  5. Isat: DC current at which the inductance drops 30% (typ) for MVR12xxC and 20% (typ) for MVR12xxT 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.

端子:

  • L = RoHS compliant tin-silver (96.5/3.5) 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)

包装:

  • C = 7" reel, 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" reel, machine-ready reel
    EIA-481 embossed plastic tape. Factory order only, not stocked.
