SER29xx Series

High Current Shielded Power Inductors

RoHS 준수 할로겐 프리 AEC-Q flag
SER29xx 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.
This is an improved version of the SER2800 series with a 3rd mounting pad for greater stability and board adhesion
  • Rugged flat wire construction
  • Exceptionally low DC resistance
  • Ferrite core for flat L vs. I characteristics
  • Magnetically shielded to minimize EMI
  • AEC-Q200 qualified

메모
  1. When ordering, specify termination code: e.g. SER2915-333KL
  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 16092A 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. When Irms is greater than Isat,Isat is the more critical specification and Irms is shown in gray type. See temperature rise vs Current.

종단 처리:

  • L = RoHS compliant tin-silver-copper over copper.
  • E = Halogen free component. RoHS compliant tin-silver over copper.
  • S = non-RoHS tin-lead (63/37). (Special order)
