Precautions For Use

• Capacitors are polarized; observe polarity to avoid damage.
• Do not exceed rated working voltage; recommended operation at 70-80% of rated voltage.
• Do not exceed rated ripple current to prevent overheating and premature failure.
• Not suitable for frequent charging and discharging unless specifically designed.
• Capacitor life is significantly affected by ambient temperature (Arrhenius' rule applies).
• Manual soldering temperature should be below 280 for less than 3 seconds; avoid direct contact with the sleeve.
• Ensure adequate space above the safety vent for proper operation.
• Avoid stressing capacitor leads or terminals during handling and soldering.
• The aluminum case is not insulated from the cathode; ensure no conductive paths are under the capacitor on the PCB.
• Store in a cool, dry, well-ventilated environment away from direct sunlight. Re-form capacitors stored for over 6 months.
• Handle with care to prevent deformation or damage.
• Surge voltage ratings are provided for short-duration over-voltages.
• Do not use in environments with water, high humidity, harmful gases, direct sunlight, radiation, severe vibration, or with halogen-containing fixatives/coatings.
