Item	Description	Key Considerations
Polarity	DC electrolytic capacitors are polarized. Polarity is marked on the capacitor body. Use bipolar capacitors when polarity is uncertain. DC electrolytic capacitors are not for AC applications.	Reversed voltage may cause short circuit or damage.
Bipolar Capacitors	Suitable for pulse circuits and polarity reverse circuits. Not for pure AC or high ripple current circuits.	N/A
Voltage Rating	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 damage the capacitor.
Ripple Current	Do not allow excessive ripple current. Generally, not more than 80% of the rated current.	Exceeding permissible ripple current causes heat, reduced capacitance, 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: increased capacitance, leakage current; decreased tg. Lower temperatures: decreased capacitance, leakage current; increased tg.
Temperature & Life Relationship	For every 10 decrease in operating temperature, the capacitor's lifespan doubles compared to its lifespan at rated temperature. Formula provided for calculation.	Life calculation formula: Ls = L0 2^((T0-Tx)/10) * (I0/Ix)^2 * ((Tm+5)/5)^2. (Note: Formula interpretation might require further context from original document for precise variable definitions.)
Operating Frequency	Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature.	Consider frequency effects on capacitance and performance.
Storage	Capacitors stored for long periods may experience increased leakage current and reduced withstand voltage. Apply rated DC voltage gradually before use.	Treatment: Gradually apply DC voltage to rated voltage before use.
Case Insulation	The capacitor case is not insulated from the cathode terminal. Insulate at the mounting point if case insulation is required.	Ensure proper insulation measures if the case needs to be isolated from the circuit.
Mechanical Stress	Do not apply excessive force to terminals and leads. Avoid bending leads too close to the capacitor body (maintain 2mm safe spacing).	Excessive force can cause lead breakage, terminal separation, or internal connection failure. Improper bending can damage internal structure.
Cleaning	Do not use halogenated solvents (e.g., trichlorethylene, xylene, acetone). Recommended solvents: Methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and general detergents.	Avoid damaging plastic sleeve, marking, and sealing materials.
Soldering	Soldering iron should be kept away from plastic sleeves. Recommended: within 260 for no more than 10 seconds when dipping in solder bath.	Prevent damage to the capacitor unit.
PCB 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 short circuits or damage. Solder splashing can cause damage.
