MS390PZA Series
High Reliability Power Inductors
MS390PZA Series features high temperature materials allowing operation in ambient temperatures up to 155°C.
- Tin-lead (Sn-Pb) termination for the best possible board adhesion.
- Low profile, ultra-miniature, shielded power inductor.
- Soft saturation makes them ideal for VRM/VRD applications.
- Tin-lead (63/37) over tin over nickel over silver terminations.

Notes
- When ordering, please specify screening code: e.g. MS390PZA222MSZ.
- Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
- DCR measured on a micro-ohmmeter.
- SRF measured using Agilent/HP 4395A or equivalent.
- DC current at 25°C that causes the specified inductance drop from its value without current.
- 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:
