Storage and Operation Conditions

• Store the capacitors at room temperature of +5°C to +40°C and a relative humidity of 20% to 70%.
• Avoid sunlight, dust, rapid temperature changes, corrosive gas atmosphere, or high temperature and humidity conditions during storage.
• Use the product within six months to prevent oxidation of the terminations.
• Confirm solderability before using after six months.
• Do not store the capacitors in an atmosphere consisting of corrosive gas (e.g., hydrogen sulfide, sulfur dioxide, chlorine, ammonia gas, etc.).

Rating

• Do not apply a voltage to the capacitor that exceeds the rated voltage.
• Confirm the operating conditions to ensure that no large current is flowing into the capacitor due to the continuous application of an AC voltage or pulse voltage.
• Consider the self-heating condition and ensure the surface temperature of the capacitor remains within the maximum operating temperature.

Soldering and Mounting

• Confirm the best mounting position and direction that minimizes the stress imposed on the capacitor during flexing or bending the printed circuit board.
• Do not re-use capacitors that were removed from the equipment.
• Confirm the mechanical stress under actual process and equipment use.
• Prior to use, confirm the solderability of capacitors that were in long-term storage.
• Prior to measuring capacitance, carry out a heat treatment for capacitors that were in long-term storage.
