Description: SMD Shielded High Current Power Inductors
Features:
1
•ꢀ
Magnetic shielded structure, excellent resistance to electro-
magnetic interference.
•ꢀ
•ꢀ
•ꢀ
Sturdy contruction.
2
3
Low magnetic loss, low ESR, small parasitic capacitance.
Closed magnetic circuit, super low buzzing, high density
mount.
Terminal 3 is for
mounting stability only.
•ꢀ
The temperature rise of current and rated current less influ-
enced by the environment.
Applications: Storage inductor for high efficiency DC/DC con-
verters, Single and polyphase buck converters, Filter for audio ap-
plications, Optimized for high current boost applications, Industrial
control PC’s, Servers, DC/DC converters, LED lighting, Communi-
cation equipment, Navigation, etc.
PAD LAYOUT
Unit: mm
Operating Temperature: -55°C to +125°C (The part temperature
(ambient + temp. rise) of the product should not exceed 125°C
in bad working condition. Circuit design, component placement,
PWB trace size and thickness, airflow and other cooling provi-
sions all affect the part temperature. Part temperature should be
verified in the final application.
