Technical Specifications

Item	Description	Key Considerations
Polarity	DC electrolytic capacitors are polarized. Polarity is marked on the capacitor body. Use bipolar capacitors when polarity is not determined or unknown. Not for AC application.	Reversed voltage may cause short circuit or damage.
Bipolar Capacitors	Suitable for pulse circuits and polarity reverse circuits. Not applicable in pure AC or high ripple current circuits.	Limited application scope.
Voltage Usage	Do not apply voltage greater than rated voltage. Recommended working voltage is 70-80% of rated voltage.	Exceeding rated voltage increases leakage current and may cause damage. Recommended voltage prolongs life.
Ripple Current	Do not allow excessive ripple current. Generally, not more than 80% of the rated current.	Excessive ripple current causes heating, capacitance reduction, and damage.
Charge/Discharge Circuits	Use specially designed capacitors for circuits with rapid charge and discharge cycles.	Standard capacitors may be damaged, leading to capacitance decrease and heat rise.
Operating Temperature	Capacitor characteristics vary with temperature. Lower temperatures ensure longer life.	Higher temperatures: capacitance/leakage increase, tg decrease. Lower temperatures: capacitance/leakage decrease, tg increase.
Temperature and Life Relationship	Life is related to operating temperature. Reducing temperature by 10 can double the life at rated temperature.	Formula provided for life calculation based on temperature and ripple current.
Operating Frequency	Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies.	Higher frequencies can increase ambient temperature.
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 voltage application is recommended.
Case Insulation	The capacitor case is not insulated from the cathode terminal. Insulation measures are required if the case must be insulated.	Case and cathode are connected via electrolyte.
Terminal/Lead Force	Do not apply excessive force to terminals and leads.	Excessive force can cause breakage, separation, and internal connection failure.
Lead Bending	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.
Circuit Board Cleaning	Do not use halogenated or similar solvents (e.g., trichlorethylene, xylene, acetone). Recommended solvents: methanol, isopropanol, ethanol, etc.	Cleaning is necessary to remove flux. Certain solvents can damage the capacitor's sleeve, marking, and sealing materials.
Soldering	Keep soldering iron away from plastic sleeves. Recommended: within 260 for no more than 10 seconds when dipping.	Avoid damage to the capacitor unit.
Hole Layout	Mounting hole spacing should equal lead spacing. Consider hole layout carefully to prevent solder splashing onto the sleeve.	Incorrect spacing can cause stress on leads, leading to shorts or circuit damage. Solder splashing can cause damage.
