Application Guidelines
Circuit Design Considerations:
- 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 heat rise from ripple current.
- Operating Temperature and Life Expectancy: Refer to the file: Life calculation of aluminum electrolytic capacitor.
- Common Application Conditions to Avoid: Reverse Voltage, repeating Charge/Discharge applications, Over voltage (exceeding rated voltage), and exceeding maximum specified ripple currents.
- Using Two or More Capacitors in Series or Parallel: Parallel connections require careful wiring to balance ripple current loads. Series connections may require shunt resistors to balance voltage.
- Capacitor Mounting Considerations: Avoid wiring patterns under mounted capacitors, ensure correct hole spacing, provide clearance for pressure relief vents, avoid high voltage wiring near vents, avoid circuit board patterns under the capacitor, and follow torque specifications for screw terminals.
- Electrical Isolation: Ensure complete isolation between cathode and case (except for B types), anode terminal and other paths, and extra mounting terminals and terminals.
Capacitor Handling Techniques:
- Before Using: Capacitors have finite life; do not reuse. Discharge transient recovery voltage if necessary. Long storage may increase leakage current, requiring reconditioning. Avoid using dropped, dented, or crushed capacitors.
- Insertion: Verify capacitance, rated voltage, and polarity. Ensure correct hole spacing. Prevent stress on leads during auto-insertion.
- Soldering: Observe temperature and time specifications. Avoid stress on leads where they enter the seal. Do not touch capacitor body with soldering iron. Avoid immersing capacitor body into solder bath during flow soldering.
- Circuit Board Cleaning: Use suitable cleaning solvents (max 60, 5 min), rinse, and dry thoroughly. Avoid halogenated, alkali, petroleum-based solvents, xylene, and acetone unless specified. Monitor contamination levels.
- Mounting Adhesives and Coating Agents: Avoid halogenated solvents and chloroprene-based polymers. Dry thoroughly.
Precautions for using capacitors:
- Environmental Conditions: Avoid temperatures outside rated range, direct contact with water/salt water/oil, high humidity, toxic gases (HS, HSO, HNO, Cl, NH), ozone, radiation, UV rays, and excessive vibration/shock.
- Electrical Precautions: Avoid touching terminals due to electric shock risk. Do not short circuit terminals with conductive materials or liquids.
Emergency Procedures:
- If pressure relief vent operates, turn off equipment immediately. Avoid contact with escaping electrolyte gas (>100). Flush eyes with water, gargle if ingested, wash skin with soap and water if contacted.
Long Term Storage:
- Leakage current increases with long storage. Recondition capacitors stored for over one year by applying rated voltage in series with a 1000 resistor for 30 minutes. Products over eighteen months old require 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.
