10. Mounting

Placement force should not be excessive.

11. Recommended Washing Condition

Since this chip inductor is a coil of ultra-thin 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:

Ultrasonic power:

Within 20W/1

Cleaning times:

Within 5 minutes

12. Storage

Chip inductors should not be stored under high temperature and high humidity conditions.

In particular, do not store

taping where it is exposed to heat or direct sunlight. Otherwise,

the packing material may be deformed, causing problems during mounting.

9. Recommended Soldering Condition

9-1 Dimensions of Standard Land

The following figure is recommended

land dimensions.

When two or more chip inductors are closely

mounted, they must be separated by means

of solder resists to prevent excessive solder.
