Vishay Dale

Manufactured under one or more of the following:

US Patents; 6,198,375/6,204,744/6,449,829/6,460,244.

Several foreign patents, and other patents pending.

Notes

T of 40 °C

125 °C under worst case operating conditions. Circuit design,

component placement, PWB trace size and thickness, airflow

and other cooling provisions all affect the part temperature. Part

temperature should be verified in the end application.

FEATURES

• Frequency range up to 5.0 MHz

• Lowest DCR/μH, in this package size

• Handles high transient current spikes without

saturation

• Ultra low buzz noise, due to composite

construction

• Compliant to RoHS Directive 2002/95/EC

APPLICATIONS

• PDA/notebook/desktop/server applications

• High current POL converters

• Low profile, high current power supplies

• Battery powered devices

• DC/DC converters in distributed power systems

• DC/DC converter for Field Programmable Gate Array (FPGA)
