MSS1278 Series

Shielded Surface Mount Power Inductors

RoHS-konform AEC-Q flag
Coilcraft MSS1278 Series shielded surface-mount power inductors feature low DC resistance and excellent current handling in a wide range of industry-standard footprints and inductance values, making them a cost-effective option for a variety of general-purpose applications. 
  • Low-loss ferrite drum core for flat inductance vs current
  • Low DC resistance for greater efficiency
  • Excellent current handling
  • Magnetic shielding allows high-density mounting
  • AEC-Q200 Grade 3 (-40°C to +85°C)

Hinweise
  1. When ordering, please specify termination and packaging codes: e.g. MSS1278-105KLD
  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 and a Coilcraft CCF858 test fixture. For other operating temperatures, use this DCR at Temperature calculator
  4. SRF measured using an Agilent/HP 4191A or equivalent.
  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.

Anschlüsse:

  • L = RoHS compliant matte tin over nickel over phos bronze.
  • 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)

Verpackung:

  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape (500 parts per full reel).
  • B = Less than full reel
    In tape, not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead.
