Notes

• All test data is referenced to 25 °C ambient

• Operating temperature range -55 °C to +125 °C

• The part temperature (ambient + temp. rise) should not exceed

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.

• Rated operating voltage (across inductor) = 40 V

T of 40 °C

FEATURES

• Shielded construction

• Excellent DC/DC energy storage up to 1 MHz to

2 MHz. Filter inductor applications up to SRF

(see “Standard Electrical Specifications” table)

• Lowest DCR/μH, in this package size

• Handles high transient current spikes without

saturation

• Ultra low buzz noise, due to composite construction

• Material categorization: for definitions of compliance

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)
