Technical Specifications

Item	Description	Key Considerations
1. Polarity	DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors for indeterminate or unknown polarity. Not for AC applications.	Marked on capacitor body. Reversed voltage causes damage.
2. Bipolar Capacitors	Suitable for pulse and polarity reverse circuits. Not for pure AC or high ripple current circuits.	Limited application scope.
3. Operating Voltage	Do not exceed 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. Generally, not to exceed 80% of rated current.	Excessive ripple current causes heating, capacitance reduction, and damage.
5. Charge/Discharge Cycles	Use specially designed capacitors for circuits with rapid charge/discharge cycles.	Standard capacitors may be damaged, leading to reduced lifespan due to 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, decrease tg. Lower temperatures decrease capacitance and leakage current, increase tg.
7. Temperature vs. Life	For every 10C reduction in temperature, life is doubled at rated temperature.	Formula provided for calculation: Ls = L0 * 2^((T0-Tx)/10) * (I0/Ix)^m (Note: Specific values for m, T0, Tx, I0, Ix, L0 are not provided in detail for a general table).
8. Operating Frequency	Capacitance is usually measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies.	Higher frequencies can also increase ambient temperature.
9. Long-Term Storage	Apply rated DC voltage treatment before use for capacitors stored for a long time.	Storage can increase leakage current and decrease withstand voltage. Gradual application of DC voltage to rated voltage is recommended.
10. Case Insulation	The capacitor case is not insulated from the cathode terminal.	Insulation measures are required at the mounting point if case insulation is necessary.
11. Terminal/Lead Force	Do not apply excessive force to terminals and leads.	Excessive force can cause lead breakage, terminal separation, or internal connection failure.
12. Bending Leads	Maintain a 2mm safe spacing between the bend and the capacitor body when bending leads for horizontal mounting.	Failure to do so may cause internal structural damage.
13. Circuit Board Cleaning	Use recommended cleaning solvents (Methanol, Isopropanol, Ethanol, etc.). Do not use halogenated solvents.	Avoid damage to sleeve, marking, and sealing materials. Halogenated solvents like trichlorethylene, xylene, or acetone are not recommended.
14. Soldering	Soldering temperature within 260C and duration not exceeding 10 seconds. Keep soldering iron away from plastic sleeves.	Avoid damage to the capacitor unit.
15. Hole Layout on PCB	Hole spacing should match lead spacing. Consider hole layout carefully to prevent solder splashing onto the sleeve.	Incorrect hole spacing can cause stress on leads, leading to short circuits or damage. Solder splashing can cause damage.
