Item	Description
Polarity	DC electrolytic capacitors are polarized. Polarity is marked on the capacitor body. Reversed voltage may cause short circuits or damage. Use bipolar capacitors when polarity is not determined or unknown. DC electrolytic capacitors cannot be used for AC applications.
Bipolar Capacitors	Suitable for pulse circuits and polarity reverse circuits only. Not applicable in pure AC or high ripple current circuits.
Voltage Usage	Do not apply voltage greater than rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life.
Ripple Current	Do not allow excessive ripple current. Exceeding permissible limits will cause heating, capacitance reduction, and damage. Generally, ripple current should not exceed 80% of the rated value.
Fast Charge/Discharge Circuits	Use specially designed capacitors for circuits with rapid charge and discharge cycles to prevent damage, capacitance decrease, and heat rise.
Operating Temperature	Capacitor characteristics vary with temperature. Lower operating temperatures ensure longer life.
Temperature and Life Relationship	Life is related to operating temperature. Reducing temperature by 10 can double the lifespan at rated temperature. Formula provided for calculation: Ls = L0 2^((T0-Tx)/10) where L0 is useful life at rated ripple current I0 and max operating temp T0; Tx is actual operating temp; Tm is 5; Ix is actual ripple current; I0 is rated ripple current.
Operating Frequency	Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature.
Long-Term Storage	Capacitors stored for extended periods may experience increased leakage current and decreased withstand voltage. Before use, gradually apply rated DC voltage.
Case Insulation	The capacitor case is not insulated from the cathode terminal. If case insulation is required, insulation measures must be taken at the mounting point.
Force on Terminals/Leads	Do not apply excessive force to terminals or leads to prevent breakage, separation, or internal connection failure.
Bending Leads	When bending leads for horizontal mounting, maintain a 2mm safe spacing from the capacitor body to avoid internal structural damage.
Circuit Board Cleaning	Use recommended cleaning solvents: 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.
Soldering	Keep soldering irons away from plastic sleeves. For solder bath dipping, recommended temperature is within 260 for no more than 10 seconds to prevent component damage.
Hole Layout on PCB	Ensure mounting hole spacing on the circuit board matches lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor body.
