CHARACTERISTICS
Description: SMD Molded Magnetically Shielded Inductors
Applications: DC/DC converter for CPU in Notebook PC, Battery
powered devices, Cellular phone LCD displays, HDD’s, DVC’s,
DCS’s, PDA, Thin type on-board power supply module, etc.
Operating Temperature: -40°C to +120°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.)
