AE541PYA Series

Outgassing Compliant Power Inductors

AE541PYA Series offers high current and very low DCR.
  • High temperature materials allow operation in ambient temperatures up to 155°C.
  • Passes NASA low outgassing specifications.
  • Passes vibration testing to 80 G and shock testing to 1000 G.
  • Tin-lead (Sn-Pb) termination for the best possible board adhesion.
  • Soft saturation makes them ideal for VRM/VRD applications.
  • Tin-lead (63/37) over copper terminations.

Notes
  1. When ordering, please specify screening code: AE541PYA682MSZ.
  2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4192A.
  3. DCR measured on a micro-ohmmeter.
  4. SRF measured using an Agilent/HP 4395A or equivalent.
  5. DC current at 25°C that causes a 30% (typ) inductance drop from its value without current.
  6. Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

    Note:
    Irms testing was performed on a 0.060′′ thick pcb with 4 oz. copper traces optimized to minimize additional temperature rise. Temperature rise is highly dependent on many factors including pcb land pattern, trace size, and proximity to other components. Therefore temperature rise should be verified in application conditions.

Screening:

  • Z = Unscreened
  • Y = Unscreened (SLDC Option A)
  • W = Unscreened (SLDC Option B)
  • H = Group A screening per Coilcraft CP-SA-10001
  • G = Coilcraft CP-SA-10001 Group A (SLDC Option A)
  • D = Coilcraft CP-SA-10001 Group A (SLDC Option B)
All screening performed to the document’s latest revision.
Custom screening also available.
