High-Reliability Power Inductors MS319PZA
■ High temperature material allows operation in ambient
temperatures up to 155°C
■ Tin-lead (Sn-Pb) termination for the best possible board
adhesion
■ 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.

1. When ordering, please specify testing code:
MS319PZA681MSZ
Testing:
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.
