Guidelines For Using Aluminum Electrolytic Capacitors

• Polarity: DC electrolytic capacitors are polarized. Ensure correct polarity to avoid damage. Not for AC application.
• Bipolar Capacitors: For pulse and polarity reverse circuits only, not for pure AC or high ripple current.
• Operating Voltage: Do not exceed rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life.
• Ripple Current: Do not exceed permissible ripple current to prevent overheating and damage. Generally not more than 80% of rated current.
• Charge/Discharge Circuits: Use specially designed capacitors for circuits with frequent charge/discharge cycles.
• Operating Temperature: Characteristics vary with temperature. Lower temperatures ensure longer life.
• Temperature and Life: Life is approximately doubled for every 10 reduction in temperature from rated temperature.
• Operating Frequency: Capacitance decreases and tg increases with rising frequency.
• Long-term Storage: Apply rated DC voltage gradually before use to mitigate increased leakage current and reduced withstand voltage.
• Case Insulation: Capacitor case is not insulated from the cathode terminal. Insulation measures are required at the mounting point if case insulation is needed.
• Terminal Force: Do not apply excessive force to terminals or leads to prevent damage.
• Cleaning: Use recommended solvents (methanol, isopropanol, ethanol, etc.). Avoid halogenated solvents.
• Soldering: Maintain distance from plastic sleeve. Solder bath temperature within 260 for no more than 10 seconds.
• Hole Layout: Ensure correct hole spacing on PCBs to avoid stress on leads. Consider solder splashing.
