2010 POWER INDUCTORS
High Reliability Power Inductors
MS338PWA
■
High temperature materials allow operation in ambient
temperatures up to 155°C
■
Very low DCR and excellent current handling.
■
Soft saturation makes them ideal for VRM/VRD applications.
■
Tin-lead (Sn-Pb) termination for the best possible board
adhesion
■
Special construction allows it to pass vibration testing to
30 G and shock testing to 500 G.
Weight

1. When ordering, please specify
testing
code:
MS338PWA224MSZ
Testing: Z
= COTS
H
= Screening per Coilcraft CP-SA-10001
N
= Screening per Coilcraft CP-SA-10004
Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
DCR measured on a micro-ohmmeter.
SRF measured using Agilent/HP 4395A or equivalent.
DC current at which the inductance drops the specified amount from its
value without current.
6. Current that causes the specified temperature rise fron 25°C ambient.
7. Electrical specifications at 25°C.
