2005 POWER INDUCTORS
High-Reliability Power Inductors
ML319PZA
■
High temperature material allows operation in ambient
temperatures up to 155°C
■
Lowest profile, ultra-miniature, magnetically shielded
power inductor; only 0.5 mm high, 2 mm × 2 mm footprint
■
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.

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 which the inductance drops the specified amount from its
value without current.
6. Current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
