Attachment: Application Guidelines

1. 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 heat.
• Operating Temperature and Life Expectancy: Refer to Life calculation of aluminum electrolytic capacitor document.
• Common Application Conditions to Avoid: Reverse Voltage (use DC bipolar for changing polarity, not for AC circuits), Repeating Charge/Discharge Applications (consult manufacturer), Over voltage (do not exceed rated voltage; sum of DC and AC ripple peak must not exceed rated voltage), Ripple Current (do not exceed specified values; use high ripple current capacitors or consult manufacturer).
• Using Two or More Capacitors in Series or Parallel: Parallel connection may cause ripple current imbalance; series connection may cause voltage imbalance due to leakage current differences.
• Capacitor Mounting Considerations: Avoid wiring patterns between capacitor and board. Prevent solder from collecting under capacitor. Ensure circuit board hole spacing matches capacitor lead spacing. Provide clearance for pressure relief vents (minimum 2mm for 6.3~16mm, 3mm for 18~35mm, 5mm for 40mm+). Ensure a hole in the circuit board under seal mounted vents. Avoid high voltage/current wiring near pressure relief vents. Avoid circuit board runs under the capacitor. For screw terminals, do not orient with the terminal side facing down. Tighten screws within specified torque range.
• Electrical Isolation: Isolate cathode from case (except axially leaded B types), anode terminal from other paths, and extra mounting terminals from anode, cathode, and other paths.
• Capacitor Sleeve: The sleeve is for marking and identification, not electrical insulation. It may split/crack with solvents like toluene/xylene and high temperatures.
• Safety Precautions: Plan for worst-case failure modes (short/open circuits). Provide protection circuits/devices. Design redundant circuits where possible.

2. Capacitor Handling Techniques

• Considerations Before Using: Capacitors have finite life; do not reuse. Discharge transient recovery voltage with a resistor (approx. 1k). Long storage may increase leakage current (recondition with rated voltage and 1k resistor). Avoid using dropped, dented, or crushed capacitors.
• Capacitor Insertion: Verify capacitance, rated voltage, and polarity. Verify hole spacing. Ensure auto insertion equipment does not stress leads at the seal.
• Manual Soldering: Observe temperature/time specs (max 400 for 3s). Avoid stress on leads at the seal. Avoid touching capacitor body with soldering iron.
• Flow Soldering: Do not immerse capacitor body in solder bath. Observe soldering conditions. Prevent other parts from touching capacitor during soldering.
• Other Soldering Considerations: Avoid rapid temperature rises during preheat/resin bonding. Do not exceed 150 for 2 minutes for heat curing.
• Capacitor Handling after Solder: Avoid moving capacitor after soldering. Do not use capacitor as a handle. Avoid striking capacitor after assembly.
• Circuit Board Cleaning: Immerse/ultrasonically clean using suitable solvents (max 5 min, 60). Rinse and dry thoroughly. Avoid ozone-depleting agents. Avoid halogenated solvents (except solvent-resistant types), alkali solvents, petroleum-based solvents, xylene, and acetone. Monitor contamination levels.
• Mounting Adhesives and Coating Agents: Avoid materials containing halogenated solvents or chloroprene-based polymers. Dry thoroughly after application.

3. Precautions for Using Capacitors

• Environmental Conditions: Do not store/use above max or below min rated temperature. Avoid direct contact with water, saltwater, oil. Avoid high humidity where condensation can occur. Avoid toxic gases (HS, HSO, HNO, Cl, NH). Avoid ozone, radiation, UV rays. Avoid vibration/shock exceeding specified requirements.
• Electrical Precautions: Avoid touching terminals (risk of electric shock). Exposed aluminum case is not insulated. Avoid short-circuiting terminals with conductive materials or liquids.

4. Emergency Procedures

• If pressure relief vent operates, immediately turn off equipment and disconnect power. Avoid contact with escaping electrolyte gas (>100). Flush eyes with water if electrolyte/gas enters. Gargle with water if ingested. Wash skin with soap and water if contact occurs.

5. Long Term Storage

• Leakage current increases with storage. Recondition after one year by applying rated voltage in series with a 1000 resistor for 30 minutes.
• Environmental Conditions for Storage: Same as 3.1.

6. 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.
