Technical Specifications

Item	Description
Polarity	DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors when polarity is uncertain. Not suitable for AC applications.
Bipolar Capacitors	Suitable for pulse circuits and polarity reverse circuits only. Not applicable for pure AC or high ripple current circuits.
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.
Ripple Current	Do not allow ripple current to exceed permissible limits. Exceeding limits can cause heating, capacitance reduction, and damage. Generally, ripple current should not exceed 80% of the rated value.
Charge/Discharge Circuits	For circuits with rapid charge/discharge cycles, use specially designed capacitors to prevent damage, capacitance decrease, and heat rise.
Operating Temperature	Capacitor characteristics vary with temperature. Lower temperatures ensure longer life. Usage at lower temperatures will ensure longer life.
Temperature & Life Relationship	Life is inversely proportional to temperature. A 10 reduction in temperature approximately doubles the capacitor's lifespan at rated temperature. Formula provided for calculation.
Operating Frequency	Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature.
Storage & Handling	For capacitors stored long-term, apply rated DC voltage gradually before use. Long storage can increase leakage current and decrease withstand voltage.
Case Insulation	The capacitor case is not insulated from the cathode terminal. Insulate the case at the mounting point if line insulation is required.
Terminal/Lead Force	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 safety distance from the capacitor body to prevent internal structural damage.
Circuit Board Cleaning	Use recommended solvents (Methanol, Isopropanol, Ethanol, Isobutanol, Petroleum ether, Propanol, detergents). Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect the capacitor body.
Soldering	Maintain distance between soldering iron and plastic sleeve. For solder bath dipping, temperature should be within 260 and duration not exceeding 10 seconds to prevent damage.
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.
