Application Guidelines

1. Circuit Design

• Operating Temperature and Frequency: Electrical parameters vary with temperature and frequency. Consider these changes in design. 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.
• Common Application Conditions to Avoid:
• Reverse Voltage: DC capacitors have polarity; verify correct insertion. Use DC bipolar for changing polarity.
• Charge / Discharge Applications: Standard capacitors are not suitable; consult for actual conditions.
• Over voltage: Do not exceed rated voltage. Surge voltage is acceptable for short periods. Ensure DC + AC ripple voltage does not exceed rated voltage.
• Ripple Current: Do not exceed maximum specified value. Use high ripple current capacitors for demanding applications. Ensure ripple current does not cause reverse voltage.
• Using Two or More Capacitors in Series or Parallel:
• Parallel: Circuit resistance can cause ripple current imbalance. Careful wiring is needed.
• Series: Leakage current differences can cause voltage imbalance. Use shunt resistors.
• Capacitor Mounting Considerations:
• Avoid wiring patterns between capacitor and board to prevent shorts.
• Prevent solder from passing through lead holes.
• Match circuit board hole spacing to capacitor lead spacing to avoid stress.
• Ensure clearance for pressure relief vents (minimum clearances provided for different diameters).
• A hole under seal mounted vents is required for pressure release.
• Avoid high voltage/current wiring above pressure relief vents.
• Avoid circuit board runs under the capacitor to prevent shorts from electrolyte leakage.
• For screw terminal capacitors, do not orient with the terminal side facing down. Tighten screws within specified torque.
• Electrical Isolation: Completely isolate capacitor from case (except B types) and other circuit paths.
• Product Endurance: Sample is the standard.
• Load or Shelf Life Test: Collect date code within 6 months products of sampling.
• Capacitor Sleeve: For marking and identification; not for electrical insulation. May split/crack with solvents and high temperatures.

CAUTION! Always consider safety. Plan for worst-case failure modes. Provide protection circuits and design redundant circuits.

2. Capacitor Handling Techniques

• Considerations Before Using: Capacitors have finite life; do not reuse. Discharge transient recovery voltage if needed. Long storage may increase leakage current; recondition with rated voltage and resistor. Avoid using dropped, dented, or crushed capacitors.
• Capacitor Insertion: Verify capacitance, rated voltage, and polarity. Verify hole spacing. Ensure auto insertion does not stress leads.
• Manual Soldering: Observe temperature and time specifications (max 400C for 3s). Avoid stress on lead wires. Avoid excessive stress during reinsertion. Do not touch capacitor with soldering iron.
• Flow Soldering: Do not immerse capacitor body. Observe soldering conditions. Do not let other parts touch capacitor.
• Other Soldering Considerations: Avoid rapid temperature rises. Do not exceed 150C for 2 minutes for heat curing.
• Capacitor Handling after Solder: Avoid movement after soldering. Do not use capacitor as a handle. Avoid striking capacitor.
• Circuit Board Cleaning: Use suitable solvents for up to 5 min at 60C. Rinse and dry thoroughly. Avoid ozone-depleting agents. Avoid halogenated, alkali, petroleum-based solvents, xylene, and acetone unless specified. Monitor contamination levels.
• Mounting Adhesives and Coating Agents: Avoid halogenated solvents and chloroprene polymers. Dry thoroughly.

3. Precautions for using capacitors

• Environmental Conditions: Do not store or use outside rated temperature range, in contact with water/salt water/oil, high humidity, toxic gases (H2S, H2SO4, HNO3, Cl2, NH3), ozone, radiation, UV rays, or exceeding vibration/shock requirements.
• Electrical Precautions: Avoid touching terminals due to electric shock risk. Do not short terminals with conductive materials or liquids.

4. Emergency Procedures

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

5. Long Term Storage

• Leakage current increases with long storage. Recondition after one year with rated voltage and 1000 resistor for 30 minutes. Return products with date code over eighteen months for confirmation.

6. Capacitor Disposal

• Incinerate after crushing or puncturing the can wall. Dispose of as solid waste. Follow local laws.
