Technical Specifications
| Item | Description |
| 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 for pure AC or high ripple current circuits. |
| 3. Voltage Rating | Do not exceed rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. |
| 4. Ripple Current | Do not exceed permissible ripple current limits. Excessive ripple current causes heating, capacitance reduction, and damage. Generally, do not exceed 80% of the rated value. |
| 5. Charge/Discharge Circuits | For circuits with frequent charge/discharge cycles, use specially designed capacitors to prevent damage, capacitance decrease, and heat rise. |
| 6. Operating Temperature | Capacitor characteristics vary with temperature. Lower temperatures ensure longer life. |
| 7. Temperature & Life Relationship | Life is inversely proportional to temperature. Reducing operating temperature by 10 can double the lifespan compared to rated temperature. (Formula provided in source document). |
| 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 | Capacitors stored for extended periods may experience increased leakage current and reduced withstand voltage. Before use, gradually apply rated DC voltage. |
| 10. Case Insulation | The capacitor case is connected to the cathode terminal. Insulate the case if required by the application at the mounting point. |
| 11. Terminal/Lead Force | Avoid applying excessive force to terminals and leads to prevent breakage, separation, or internal connection failure. |
| 12. Bending Leads | When bending leads for horizontal mounting, maintain a 2mm safe distance from the capacitor body to prevent internal structural damage. |
| 13. Circuit Board Cleaning | Use recommended cleaning solvents (Methanol, isopropanol, ethanol, etc.). Avoid halogenated agents or solvents like trichlorethylene, xylene, or acetone to protect the capacitor body. |
| 14. Soldering | Maintain distance between soldering iron and plastic sleeve. For solder bath dipping, recommendable temperature is within 260 for no more than 10 seconds to prevent damage. |
| 15. Hole Layout | Ensure mounting hole spacing matches lead spacing on circuit boards to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor body. |
