• Perfluorooctane sulfonates (PFOS)
• Specific Benzotriazole

Application Guidelines - Circuit Design

• Operating Temperature and Frequency: Electrical parameters vary with temperature and frequency. Higher temperatures increase leakage current and capacitance, decrease ESR. Lower temperatures decrease leakage current and capacitance, increase ESR. Higher frequencies decrease capacitance and impedance, increase tan. Lower frequencies increase ESR, leading to ripple current generated heat.
• Operating Temperature and Life Expectancy: Refer to the file: Life calculation of aluminum electrolytic capacitor.
• Common Application Conditions to Avoid: Reverse Voltage, Charge/Discharge Applications, Over voltage, Ripple Current, Pulse Current.
• Using Two or More Capacitors in Series or Parallel: Parallel connections require careful wiring to balance ripple current loads. Series connections require voltage divider shunt resistors to prevent voltage imbalances due to leakage current differences.
• Capacitor Mounting Considerations: Avoid wiring patterns under capacitors, ensure correct hole spacing, provide clearance for pressure relief vents, avoid high voltage wiring near vents, and do not orient screw terminal capacitors facing downwards.
• Electrical Isolation: Ensure complete isolation between cathode and case, anode terminal and other paths, and extra mounting terminals.

Capacitor Handling Techniques

• Considerations Before Using: Capacitors have a finite life; do not reuse from used equipment. Discharge transient recovery voltage with a resistor (approx. 1k) if needed. Long storage may increase leakage current, correctable by gradual voltage application with a 1k resistor. Avoid using dropped, dented, or crushed capacitors.
• Capacitor Insertion: Verify capacitance, rated voltage, polarity, and hole spacing. Ensure auto insertion equipment does not stress leads at the seal.
• Manual Soldering: Observe temperature and time specifications (do not exceed 400 for 3 seconds). Avoid stressing lead wires at the seal. Avoid touching the capacitor body with the soldering iron.
• Flow Soldering: Do not immerse the capacitor body into the solder bath. Observe proper soldering conditions.
• Other Soldering Considerations: Avoid rapid temperature rises during preheat and resin bonding.
• Capacitor Handling after Solder: Avoid movement after soldering. Do not use capacitors as handles. Avoid striking capacitors after assembly.
• Circuit Board Cleaning: Use suitable cleaning solvents for up to 5 minutes at 60 max. Rinse and dry thoroughly. Avoid halogenated, alkali, petroleum-based solvents, xylene, and acetone unless specified. Monitor contamination levels.
• Mounting Adhesives and Coating Agents: Avoid materials containing halogenated solvents or chloroprene-based polymers. Dry thoroughly after application.

Precautions for Using Capacitors

• Environmental Conditions: Do not store or use outside rated temperature ranges, in direct contact with water/oil, high humidity, toxic gases, ozone, radiation, UV rays, or exceeding vibration/shock requirements.
• Electrical Precautions: Avoid touching terminals due to electric shock risk. Do not short circuit terminals with conductive materials.

Emergency Procedures

• If the pressure relief vent operates, immediately turn off equipment and disconnect power. Avoid contact with escaping electrolyte gas. Flush eyes with water if electrolyte enters, gargle if ingested, wash skin with soap and water.

Long Term Storage

Leakage current increases with long storage times. Recondition capacitors stored for over one year by applying rated voltage in series with a 1000 current limiting resistor for 30 minutes. Products with date codes over eighteen months should be returned for confirmation.

Capacitor Disposal

• Incinerate after crushing or puncturing to prevent explosion. Incinerate at high temperatures to prevent toxic gas release. Dispose of as solid waste. Follow local laws for disposal requirements.
