ML322PZA Series
High Reliability Power Inductors
ML322PZA Series features special construction allowing it to pass vibration testing to 80 G and shock testing to 1000 G.
- High temperature materials allow operation in ambient temperatures up to 155°C.
- Lowest profile, ultra-miniature, shielded power inductor.
- Soft saturation makes them ideal for VRM/VRD applications.
- Tin-silver over copper terminations.

Notes
- When ordering, please specify screening code: e.g. ML322PZA104MLZ.
- 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.
