2-2. Dimensions of Slit (Example)
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.
A longer slit design might receive more severe
mechanical stress from the PCB.
Recommended slit design is shown in the Table.
