SER14xx Series

High Current Shielded Power Inductors

RoHS compliant halogen free AEC-Q flag
SER14xx 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
  • AEC-Q200 Grade 1 (−40°C to +125°C) — SER1412 only

Notes
  1. When ordering, please specify termination and packaging codes: e.g. SER1410-202MED
  2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4263B LCR meter or equivalent.
  3. DCR measured at 25°C on a micro-ohmmeter and a Coilcraft CCF840 test fixture. 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: Typical dc current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
  6. Irms: Typical 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:

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

Packaging:

  • D = 13" machine-ready reel
    EIA-481 embossed plastic tape
  • SER1408: 300 parts/full reel;  SER1410SER1412: 250 parts/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.
