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' file.
• Common Application Conditions to Avoid: Reverse Voltage, Repeating Charge/Discharge Applications, Over voltage, Ripple Currents exceeding maximum specified value.
• 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 balance voltage.
• Capacitor Mounting Considerations: Avoid wiring patterns under capacitors, ensure correct hole spacing, provide clearance for pressure relief vents, avoid high voltage wiring near vents, avoid circuit board runs under the capacitor, follow torque specifications for screw terminals.
• Electrical Isolation: Ensure proper isolation between cathode/case, anode terminal/other paths, and extra mounting terminals.
• Capacitor Sleeve: Vinyl sleeve is for marking and identification, not electrical insulation. May split/crack with certain solvents and high temperatures.
• Safety Precautions: Plan for worst-case failure modes, provide protection circuits, design redundant circuits.

2. Capacitor Handling Techniques

• Considerations Before Using: Capacitors have finite life, do not reuse. Discharge transient recovery voltage if needed. Long-term storage may increase leakage current (recondition if necessary). Avoid using dropped or dented capacitors.
• Capacitor Insertion: Verify capacitance, rated voltage, and polarity. Ensure correct hole spacing. Prevent auto-insertion equipment from stressing leads.
• Manual Soldering: Observe temperature and time specifications. Avoid stressing leads during forming. Avoid excessive stress during reinsertion. Do not touch capacitor body with soldering iron.
• Flow Soldering: Do not immerse capacitor body into solder bath. Observe proper soldering conditions. Prevent other components from touching capacitor during soldering.
• Other Soldering Considerations: Avoid rapid temperature rises during preheat/resin bonding.
• Capacitor Handling after Solder: Avoid movement after soldering. Do not use capacitor as a handle. Avoid striking capacitor after assembly.
• Circuit Board Cleaning: Use suitable cleaning solvents, rinse and dry thoroughly. Avoid ozone-depleting agents. Specific solvent groups (Halogenated, Alkali, Petroleum based, Xylene, Acetone) may cause damage. 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: Avoid storage/use outside rated temperature range, direct contact with water/salt water/oil, high humidity, toxic gases, ozone/radiation/UV rays, excessive vibration/shock.
• Electrical Precautions: Avoid touching terminals due to electric shock risk. Do not short circuit terminals with conductive materials.

4. Emergency Procedures

• If pressure relief vent operates, immediately turn off equipment. Avoid contact with escaping electrolyte gas. Follow first aid procedures for eye/mouth/skin contact.

5. Long Term Storage

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