Technical Specifications
The following sections detail critical parameters and usage guidelines for Aluminum Electrolytic Capacitors.
General Usage Guidelines
| Section | Description | Key Considerations |
|---|---|---|
| 1. Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors if polarity is uncertain. Not for AC applications. | Marked on capacitor body. Reversed voltage can cause damage. |
| 2. Bipolar Capacitors | Suitable for pulse and polarity reverse circuits. Not for pure AC or high ripple current circuits. | Limited application scope. |
| 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 can cause damage. |
| 4. Ripple Current | Do not allow excessive ripple current. Generally, not to exceed 80% of the rated value. | Excessive ripple current causes heating, capacitance decrease, and damage. |
| 5. Charge/Discharge Cycles | Use specially designed capacitors for circuits with rapid charge and discharge cycles. | Rapid cycles can shorten lifespan due to capacitance decrease and heat rise. |
| 6. Operating Temperature | Capacitor characteristics vary with temperature. Lower temperatures generally ensure longer life. | Higher temperatures: capacitance/leakage increase, tg decrease. Lower temperatures: capacitance/leakage decrease, tg increase. |
| 7. Temperature & Life Relationship | Life is inversely proportional to temperature. A 10C decrease in temperature approximately doubles the lifespan. | Formula provided for life calculation based on temperature and current. |
| 8. Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies. | Higher frequencies can lead to increased ambient temperature. |
| 9. Long-Term Storage | Capacitors stored for extended periods may experience increased leakage current and reduced withstand voltage. Treat with rated DC voltage before use. | Gradually apply DC voltage to rated voltage before use. |
| 10. Case Insulation | The capacitor case is not insulated from the cathode terminal. Insulation measures are required if the case needs to be insulated from the circuit. | Case and cathode are connected via electrolyte. |
| 11. Terminal/Lead Force | Do not apply excessive force to terminals and leads to prevent breakage or internal connection failure. | Avoid mechanical stress on terminals and leads. |
| 12. Bending Leads | Maintain a 2mm safe spacing from the capacitor body when bending leads to prevent internal structural damage. | Ensure proper bending technique to avoid damage. |
| 13. Circuit Board Cleaning | Use recommended cleaning solvents (e.g., methanol, ethanol) and avoid halogenated solvents (e.g., trichlorethylene) to protect the capacitor. | Recommended solvents: Methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and detergents. |
| 14. Soldering | Maintain distance between soldering iron and plastic sleeve. Recommended: within 260C for no more than 10 seconds. | Avoid damage to the capacitor unit during soldering. |
| 15. Hole Layout | Ensure hole spacing on circuit boards matches lead spacing to avoid stress on leads. Consider hole layout to prevent solder splashing onto the capacitor. | Proper hole placement prevents mechanical stress and potential damage. |
