 Qualified to IPC9592B, Class II
 MSL3 and RoHS compliant
All SPM1005 models deliver full 6A load current without
derating at 85°C ambient temperature with no airflow.
APPLICATIONS
 Broadband and communications equipment
 DSP and FPGA Point of Load applications
 High density distributed power systems
 Systems using PCI / PCI express / PXI express
 Automated test and medical equipment
Small size (11mm x 9mm) and low profile (3mm) allows
the SPM1005 to be placed very close to its load or on the
back side of the PCB for high density applications.
Sumida's PSI² technology ensures optimal inductor
design, uniform temperature distribution and very low
temperature difference between case and IC die.
