D1787 Series

SMT Power Inductor for Texas Instruments LM5115DC

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

注释

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.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. Details
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.
