D1787 Series

SMT Power Inductor for Texas Instruments LM5115DC

RoHS-konform
D1787 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.
  • Developed for Texas Instruments LM5115DC Post Regulator Controller
  • Core shape allows excellent heat dissipation.
  • Rugged flat wire construction
  • Exceptionally low DC resistance
  • Ferrite core for flat L vs. I characteristics
  • Magnetically shielded to minimize EMI

Hinweise
  1. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-D fixture in an Agilent/HP 4263B impedance analyzer or equivalent.
  2. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  3. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. Details
  4. Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
