YAGEO CORPORATION
SMD INDUCTOR / BEADS
SMD Power Inductors
SSL1306HC Series
These series have been specially designed for high current, low voltage DC-DC converter applica-
tions.
This simple, rugged design provides current ratings normally available only in much larger packages
- up to 16Arms for a .33µH part. With its tinned self-leaded construction, the SSL0804HC achieves
very low DCR values and excellent solderability. In addition to the standard parts shown, custom val-
ues are also available.
These inductors are less than .2’ (5mm) high. They have very low resistance and a rugged self-
leaded construction.
fEATURES
For high current, low voltage DC-DC converter
applications.
AppLICATIonS

• Note: YAGEO will start to release SSL_HC
Series inductors with lead-free terminals
which meet SONY SS-00259's criteria
for lead-free product in Q2 of 2004, and
YAGEO Internal No will be changed to ‘N’
as identification. Ex. SSL0503HC-R56M-N
