Inductors
Wound Type for Power Circuit
SMD
These products are low height type power inductors optimum to a
DC-DC converter for driving an LCD panel. A plane accuracy of a
user terminal is increased by separating a winding terminal. In
addition, an application of a new-designed thin type drum core sig-
nificantly lowers leakage flux so as to satisfy needs for high density
mounting.

FEATURES
(2) DimensionsL×W×T
• The first low height realized by using new magnetic material
superior in superimposed DC current characteristics with high
specific resistance and by adopting a design in which a lead
frame is directly bonded.

T
Taping(reel)
• Mountable on the back side of the LCD surface because of low
height type (1.20mm max.).
(4) Inductance value
• Low leakage flux drum core with original design applied.
• Size equivalent to a half of a conventional core having the same
characteristics realized, thus enabling light weight (0.1g max.).
• Automatic inserter usable in taping specifications.
• All terminals are welded without lead.
