7.Vibration and Shock

1. The capacitors mechanical actress (vibration and shock) shall be specified for the use environment.
    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 falling may cause damage or a crack in the dielectric material of the capacitor.
    Do not use a fallen capacitor because the quality and reliability may be deteriorated.

3. When printed circuit boards are piled up or handled, the corners 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.

 Soldering and Mounting

1.Mounting Position

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.

 

[Component Direction]

Locate chip horizontal to the
