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 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 permissible limits causes heating, capacitance reduction, and damage. Ripple current should generally not exceed 80% of the rated value. |
| 5. Charge/Discharge Circuits | For circuits with rapid 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. At higher temperatures, capacitance and leakage current increase, and tg decreases. At lower temperatures, capacitance and leakage current decrease, and tg increases. |
| 7. Temperature & Life Relationship | Capacitor life is related to operating temperature. A 10C reduction in temperature can double the lifespan compared to the rated temperature. Formula provided for calculation: Ls = L0 * 2^((T0 - Tx - Tm) / 10) where L0 is useful life at rated ripple current I0 and max operating temp T0. Tx is actual operating temp, Ix is actual ripple current, Tm is 5C. |
| 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 have increased leakage current and reduced withstand voltage. Before use, gradually apply rated DC voltage. |
| 10. Case Insulation | The capacitor case is not insulated from the cathode terminal. If insulation is required, implement it 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 spacing from the capacitor body to prevent internal structural damage. |
| 13. Cleaning | Clean circuit boards with recommended solvents like methanol, isopropanol, ethanol, isobutanol, petroleum ether, propane, or commercial detergents. Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect the sleeve, marking, and sealing materials. |
| 14. Soldering | Maintain distance between the soldering iron and the plastic sleeve. Recommended soldering temperature is within 260C for no more than 10 seconds to avoid damaging the capacitor unit. |
| 15. Hole Layout | Ensure mounting hole spacing on the circuit board matches lead spacing to prevent stress on leads, short circuits, or circuit damage. Consider hole layout carefully to prevent solder splashing onto the plastic sleeve. |
