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 the slit helps flux cleaning and resin
coating on the back of the capacitor.
However, the length of the slit design should
be as short as possible to prevent mechanical
damage in the capacitor.
(in mm)
A longer slit design might receive more severe
mechanical stress from the PCB.
Recommended slit design is shown in the
Table.
