Multilayer Ceramic Chip Capacitors
Surface Mounting Information
Dimensions for recommended typical land
General, High-Voltage
(Unit: mm)
Since the amount of solder (size of fillet) to be used has direct
influence on the capacitor after mounting, the sufficient consideration
is necessary.
When the amounts of solder is too much, the stress that a capacitor
receives becomes larger. It may become the cause of a crack in
the capacitor. When the land design of printed wiring board is
considered, it is necessary to set up the form and size of land pattern
so that the amount of solder is suitable.

Ideal Solder Height
Chip Capacitor
T/ 2 or 0.5mm
Design of printed circuit and Soldering
The recommended fillet height shall be 1/2 of the thickness of
capacitors or 0.5mm. When mounting two or more capacitors in the
common land, it is necessary to separate the land with the solder resist
strike so that it may become the exclusive land of each capacitor.
