YAGEO CORPORATION
SMD INDUCTOR / BEADS
SMD Power Inductors
SDS0402 Series
These shielded ultra-miniature inductors can help designers achieving significantly longer battery life
in handheld communication devices and other portable products.
The SDS0402 Series offers the highest efficiency, smallest size and lowest cost of any comparable
part. DC resistance is 10% to 60% lower than other inductors, with greatest efficiency improvements
seen at inductance values from 100 to 10,000µH.
These magnetically shielded inductors are designed with a flat top and constructed of heat resis-
tanct materials to ensure trouble-free assembly and reflow operations.

• Packaging: T: Tape and Reel
• Tolerance: M±20%
• Note: YAGEO will start to release SDS Series
inductors with lead-free terminals which
meet SONY SS-00259's criteria for lead-
free product in Q2 of 2004, and YAGEO
International No. will be changed to “N”
as identification. Ex.: SDS0402BL-101M-N.
