Caution
7. Vibration and Shock
1. Please confirm the kind of vibration and/or shock, its
condition, and any generation of resonance.
Please mount the capacitor so as not to generate
resonance, and do not allow any impact on the terminals.
2. Mechanical shock due to being dropped may cause
damage or a crack in the dielectric material of the
capacitor.
Do not use a dropped capacitor because the quality and
reliability may be deteriorated.
3. When printed circuit boards are piled up or handled, the
corner of another printed circuit board should not be
allowed to hit the capacitor, in order to avoid a crack or
other damage to the capacitor.

Mounting printed circuit board
c Soldering and Mounting
1. Confirm the best mounting position and direction that
minimizes the stress imposed on the capacitor during
flexing or bending the printed circuit board.
1-1. Choose a mounting position that minimizes the
stress imposed on the chip during flexing or bending
of the board.
1. Mounting Position
Continued on the following page.
Locate chip
horizontal to the
direction in
which stress
acts.
It is effective to implement the following measures, to reduce stress
in separating the board.
It is best to implement all of the following three measures; however,
implement as many measures as possible to reduce stress.
[Component Direction]
[Chip Mounting Close to Board Separation Point]
When a capacitor is mounted near a screw hole, it may be affected
by the board deflection that occurs during the tightening of the
screw. Mount the capacitor in a position as far away from the screw
holes as possible.
