MS322PZA Series

High Reliability Power Inductors

MS322PZA Series features soft saturation making them ideal for VRM/VRD applications.
  • High temperature materials allow operation in ambient temperatures up to 155°C.
  • Tin-lead (Sn-Pb) termination for the best possible board adhesion.
  • Lowest profile, ultra-miniature, shielded power inductor.
  • Special construction allows it to pass vibration testing to 80 G and shock testing to 1000 G.
  • Tin-lead (63/37) over copper terminations.

Notes
  1. When ordering, please specify screening code: e.g. MS322PZA104MSZ.
  2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
  3. DCR measured on a micro-ohmmeter.
  4. SRF measured using Agilent/HP 4395A or equivalent.
  5. DC current at 25°C that causes the specified 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.

Screening:

  • Z = Unscreened
  • 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.
