Coilcraft ML390PZA High reliability power inductor Datasheet

3010 POWER INDUCTORS
High Reliability Power Inductors ML390PZA
■ High temperature materials allow operation in ambient
temperatures up to 155°C
■ Low profile, ultra-miniature, shielded power inductor
■ Soft saturation makes them ideal for VRM/VRD applications.
Terminations Tin-silver-copper over tin over nickel over silver.

1. When ordering, please specify testing code:
ML390PZA222MLZ
Z = COTS
H = Screening per Coilcraft CP-SA-10001
N = Screening per Coilcraft CP-SA-10004
C = Custom screening (please specify when ordering)
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. Typical dc current at which the inductance drops the specified amount from its value without current.
6. Typical current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
