Usage Guidelines

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

2. Bipolar Capacitors: Suitable for pulse and polarity reverse circuits, but not for pure AC or high ripple current.

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 excessive ripple current, which causes heating, capacitance reduction, and damage. Keep ripple current within allowable limits, generally not exceeding 80% of rated value.

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 temperatures ensure longer life.

7. Temperature and Life Relationship: Capacitor life is temperature-dependent. Reducing operating temperature by 10 can double the lifespan compared to rated temperature. Formula provided for life calculation.

8. Operating Frequency: Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature.

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

10. Case Insulation: The capacitor case is connected to the cathode terminal. Insulate the case from the circuit if necessary at the mounting point.

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

12. Bending Leads: Maintain a 2mm safety distance between the bent lead and the capacitor body to avoid structural damage.

13. Cleaning: Use recommended cleaning solvents (Methanol, Isopropanol, Ethanol, etc.). Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect markings and sealing materials.

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

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