Guidelines For Using Aluminum Electrolytic Capacitor

1. Polarity: DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors for uncertain polarity. Not suitable for AC applications.

2. Bipolar Capacitors: Suitable for pulse and polarity reverse circuits only. Not applicable for pure AC or high ripple current circuits.

3. Voltage: Do not exceed rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life.

4. Ripple Current: Do not allow ripple current to exceed permissible limits (generally not more than 80% of rated value) to prevent overheating and damage.

5. Rapid Charge/Discharge: Use specially designed capacitors for circuits with frequent charge/discharge cycles to prevent damage and premature failure.

6. Operating Temperature: Capacitor characteristics vary with temperature. Lower operating temperatures ensure longer life.

7. Temperature and Life Relationship: Life is approximately doubled for every 10 decrease in temperature from the rated temperature. Formula provided for calculation.

8. Operating Frequency: Capacitance decreases and tg increases with rising frequency, potentially increasing ambient temperature. Capacitance is typically measured at 100Hz or 120Hz.

9. Long-Term Storage: For capacitors stored for extended periods, apply rated DC voltage gradually before use to restore leakage current and withstand voltage.

10. Case Insulation: The capacitor case is not insulated from the cathode terminal. Insulate at the mounting point if case insulation is required.

11. Terminal/Lead Force: Do not apply excessive force to terminals or leads to prevent breakage, separation, or internal connection failure.

12. Bending Leads: When bending leads for horizontal mounting, maintain a 2mm safe spacing from the capacitor body to prevent internal structural damage.

13. Circuit Board Cleaning: Use recommended solvents (Methanol, Isopropanol, Ethanol, etc.) for cleaning after soldering. Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect the capacitor body.

14. Soldering: Maintain distance between soldering iron and plastic sleeve. Recommended solder bath temperature is within 260 for no more than 10 seconds.

15. Hole Layout: Ensure circuit board hole spacing matches lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor body.
