Technical Specifications

Item	Description
1. Polarity	DC electrolytic capacitors are polarized. Ensure correct polarity to avoid short circuits or damage. Use bipolar capacitors if polarity is uncertain. DC electrolytic capacitors are not suitable for AC applications.
2. Bipolar Capacitors	Suitable for pulse circuits and polarity reverse circuits. Not applicable for pure AC or high ripple current circuits.
3. Voltage Application	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. Keep ripple current at or below the allowable level, generally not more than 80% of the rated current.
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. Higher temperatures increase capacitance and leakage current, while decreasing tg. Lower temperatures decrease capacitance and leakage current, while increasing tg.
7. Temperature vs. Life	Capacitor life is related to operating temperature. Reducing the temperature by 10 can double the lifespan at rated temperature. Formula provided for calculation: Ls = L0 * 2^((T0 - Tx)/10) * (I0/Ix)^m, where L0 is useful life at ripple current I0 and max temp T0; T0 is max operating temp; Tx is actual operating temp; I0 is rated ripple current; Ix is actual ripple current; m is a constant.
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 not insulated from the cathode terminal. If case insulation is required, implement insulation measures 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	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 solvents like Methanol, Isopropanol, Ethanol, Isobutanol, Petroleum Ether, Propanol, and general detergents. Avoid halogenated solvents (e.g., trichlorethylene, xylene, acetone) to protect the sleeve, marking, and sealing materials.
14. Soldering	Maintain distance between the soldering iron and the plastic sleeve. For solder dipping, recommended temperature is within 260 for no more than 10 seconds to avoid damaging the capacitor unit.
15. Hole Layout	Ensure mounting hole spacing on circuit boards matches lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor sleeve.
