• Manufacturer Part Number: NLFC322522T-681K-PF
• Description: INDUCTORS
• Manufacturer: TDK Corporation

TDK's original rational production line was the world's first.
Now, the NL family is making an effort to switch to further simplification of
resource-saving automated production lines.
The molding processes shown on the bottom right are the
conventional processes using thermosetting resin.
A new molding process shown on the bottom left deletes
processes such as " thermosetting promotion ", "omitting
burrs", and "smoothing processes" from these convention-
al processes and uses thermoplastic resin which can be
collected and reused. With a process design skillfully utiliz-
Internal structure
TDK's original design know-how is integrated in the structure as
well. For example, an examination of the drawing point of the
windings: 360 degrees is useful. It can be drawn from any angle
and inductance value configurations perfor-
med, which are delicate and subtle with
much freedom and precision. Also, simple
yet sophisticated original know-
how, such as a method
of unifying the sides of
drum cores, winding
ends, and connection
terminals, and a shape
design for connection
terminals seeking imple-
mentation reliability, are
integrated everywhere.

ing the physical properties of this resin, which allows the
control of viscosity through temperature control, a fully
automated production line was built.
The series with the " V " suffix in its title is the new product
type from this line. Shifting to the new product type is un-
derway in order to respond to cost-saving needs and for
maximized environmental conservation.
