9. General Information
(1) Storage
(5) Pattern design
Chip inductors shall not be stored under high
temperature and high humidity conditions.
Especially, do not store taping where they are
exposed to heat or direct sunlight. Otherwise,
the packing material may be deformed,
causing problems during mounting.
The land pattern is recommended as follows.

(3) Soldering
Dimensions in inches (mm)
Flow soldering should be done at 260°C
for less than 10 seconds. Reflow soldering
should be done at 240°C for less than 30
seconds. When using a soldering iron,
temperature shall not exceed 350°C and
within 3 seconds. Soldering iron time of each
electrode shall be allowed only one time.
After soldering, chip inductors shall not be
stressed excessively.
(4) Cleaning
There is no problem using organic solvents.
Since this chip inductor is a coil of ultra-fine
wire, it is susceptible to vibration. If an
ultrasonic cleaning unit is used for cleaning,
check for any possibility of problem generation
before practical use since such cleaning units
considerably differ in vibration level and mode.
Although the conditions differ depending
on the printed board size, ultrasonic cleaning
is generally used in the conditions described
below as examples.
Power: Within 20 W/L
Cleaning times: Within 5 minutes
