Coilcraft ML319PZA471MSZ High-reliability power inductor Datasheet

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.
Core material Composite
Terminations Tin-silver-copper (96.5/3/0.5) over tin over nickel over
silver-platinum.

1. When ordering, please specify testing code:
ML319PZA681MSZ
Z = COTS
H = Screening per Coilcraft CP-SA-10001
N = Screening per Coilcraft CP-SA-10004
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.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
