SER1512 Series

High Current Shielded Power Inductors

RoHS compliant halogen free
SER1512 Series high-current, high-inductance power inductors feature a flat-wire construction, resulting in exceptionally low DC resistance. They come in a wide range of sizes and inductance values for POL, VRM, VRD, and other high power applications.
  • Rugged flat wire construction
  • Exceptionally low DC resistance
  • Ferrite core for flat L vs. I characteristics
  • Magnetically shielded to minimize EMI

  1. When ordering, please specify termination and packaging codes: e.g. ser1512-223MED
  2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc, using an Agilent/HP 4284A 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 using an Agilent/HP 4395A network analyzer and an Agilent/HP 16193A test 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.



  • E = RoHS compliant matte tin over nickel over phos bronze.
  • T = RoHS tin-silver-copper over copper(95.5/4/0.5). (Special order, added cost)
  • S = non-RoHS tin-lead (63/37). (Special order, added cost)


  • D = 13" machine-ready reel
    EIA-481 embossed plastic tape (250 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.
