Inductors
For General Applications
SMD
FEATURES
• High-reliability monolithic structure.
• Ferrite core and magnetic shielding enables the design of com-
pact circuits with high packing density.
• Excellent solderability and high heat resistance permits either
flow or reflow soldering.
APPLICATIONS
Personal computers, HDDs, or other various electronic appliances.

HANDLING AND PRECAUTIONS
• Before soldering, be sure to preheat components.
The preheating temperature should be set so that the tempera-
ture difference between the solder temperature and product
temperature does not exceed 150°C.
• After mounting components onto the printed circuit board, do not
apply stress through board bending or mishandling.
• The inductance value may change due to magnetic saturation if
the current exceeds the rated maximum.
• Do not expose the inductors to stray magnetic fields.
• Avoid static electricity discharge during handling.
• When hand soldering, apply the soldering iron to the printed cir-
cuit board only. Temperature of the iron tip should not exceed
300°C. Soldering time should not exceed 3 seconds.
Specifications which provide more details for the proper and safe use of the described product are available upon request.
