SER3018H Series

High Current Shielded Power Inductors

RoHS-konform Halogenfrei
SER3018H 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.
  • Mounting plate with three pads for excellent board adhesion
  • Rugged flat wire construction
  • Exceptionally low DC resistance
  • Ferrite core for flat L vs. I characteristics
  • Magnetically shielded to minimize EMI

Hinweise
  1. When ordering, please specify termination code: e.g. SER3018H-333KE
  2. Inductance measured at 500 kHz, 0.1 Vrms, using an Agilent/HP 4284A LCR meter or equivalent.
  3. DCR measured at 25°C on a Keithley 580 micro-ohmmeter or equivalent. 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.

Anschlüsse:
