2006 POWER INDUCTORS
High Reliability Power Inductors
ML322PZA
■
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.
■
Special construction allows it to pass vibration testing to
80 G and shock testing to 1000 G.
