Technical Specifications
| Item | Description |
| 1. Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to avoid short circuits or damage. Use bipolar capacitors for uncertain polarity. Not suitable for AC applications. |
| 2. Bipolar Capacitors | Suitable for pulse circuits and polarity reverse circuits. Not applicable in pure AC or high ripple current circuits. |
| 3. Voltage Rating | Do not exceed the rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. Exceeding rated voltage increases leakage current and may cause damage. |
| 4. Ripple Current | Do not allow excessive ripple current. Exceeding the permissible limit causes heating, capacitance reduction, and damage. Generally, ripple current should not exceed 80% of the rated value. |
| 5. Charge/Discharge Circuits | Use specially designed capacitors for circuits with frequent charge and discharge cycles to prevent damage, capacitance decrease, and heat rise. |
| 6. Operating Temperature | Capacitor characteristics vary with temperature. Lower operating temperatures ensure longer life. |
| 7. Temperature and Life Relationship | Generally, reducing operating temperature by 10 doubles the lifespan compared to rated temperature. Formula provided for calculation: Ls = L0 * 2^((T0-Tx)/10) * (I0/Ix)^m (where m=0.5 for aluminum electrolytic capacitors). |
| 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, apply rated DC voltage gradually. |
| 10. Case Insulation | The capacitor case is not insulated from the cathode terminal. Insulation measures must be taken at the mounting point if the case requires insulation. |
| 11. Force on Terminals/Leads | 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 spacing from the capacitor body to prevent internal structural damage. |
| 13. Circuit Board Cleaning | Use recommended cleaning solvents: Methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and general detergents. Avoid halogenated solvents (e.g., trichlorethylene, xylene, acetone) to protect sleeve, marking, and sealing materials. |
| 14. Soldering | Maintain distance between soldering iron and plastic sleeve. Recommended solder bath temperature: within 260 for no more than 10 seconds to avoid damage. |
| 15. Hole Layout on PCB | Ensure mounting hole spacing matches lead spacing to prevent stress on leads. Consider hole layout to prevent solder splashing onto the capacitor body. |
