Coilcraft MS322PZA223MSZ High reliability power inductor Datasheet

2006 POWER INDUCTORS
High Reliability Power Inductors MS322PZA
■ High temperature materials allow operation in ambient
temperatures up to 155°C
■ Tin-lead (Sn-Pb) termination for the best possible board
adhesion
■ 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.
Terminations Tin-lead (63/37) over copper.

1. When ordering, please specify testing code:
MS322PZA222MSZ
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. 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.
