Notice (Soldering and Mounting)
1. Construction of Board Pattern
After installing chips, if solder is excessively applied to
the circuit board, mechanical stress will cause destruction
resistance characteristics to lower. To prevent this, be
extremely careful in determining shape and dimension
before designing the circuit board diagram.

Preparing slit helps flux cleaning and resin
coating on the back of the capacitor.
But, the length of slit design should be shorter
enough as much as possible to prevent the
mechanical damage in the capacitor.
The longer slit design might receive more
severe mechanical stress from the PCB.
Recommendable slit design is shown in the
Table.
