CHARACTERISTICS

Description: SMD Shielded High Current Power Inductors

Features:

•ꢀ

Magnetic shielded structure, excellent resistance to electro-

magnetic interference.

•ꢀ

Sturdy contruction.

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.
