6. Capacitance Aging

1. The high dielectric constant type capacitors have an Aging characteristic in which the capacitance

value decreases with the passage of time.

When you use a high dielectric constant type capacitors in a circuit that needs a tight (narrow)

capacitance tolerance (e.g., a time-constant circuit), please carefully consider the characteristics

of these capacitors, such as their aging, voltage, and temperature characteristics.

In addition, check capacitors using your actual appliances at the intended environment and

operating conditions.

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.
