Technical Specifications

Parameter	Description
Polarity	DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors when polarity is uncertain. DC electrolytic capacitors are not for AC applications.
Bipolar Capacitors Usage	Suitable for pulse circuits and polarity reverse circuits only. Not applicable for pure AC or high ripple current circuits.
Voltage Application	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 causes heat, 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 generally ensure longer life. Usage at lower temperatures will ensure longer life.
Temperature and Life Relationship	Life is inversely proportional to temperature. A 10C reduction in temperature can double the lifespan compared to rated temperature. Formula provided for calculation.
Operating Frequency	Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and Equivalent Series Resistance (ESR) increases with higher frequencies, leading to increased ambient temperature.
Storage and Usage	For capacitors stored long-term, apply rated DC voltage gradually before use. Long storage may increase leakage current and decrease withstand voltage.
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.
Terminal/Lead Force	Do not apply excessive force to terminals and 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 prevent internal structural damage.
Circuit Board Cleaning	Clean circuit boards using recommended solvents (Methanol, Isopropanol, Ethanol, etc.). Avoid halogenated solvents (trichlorethylene, xylene, acetone) to protect the capacitor body.
Soldering Precautions	Maintain distance between soldering iron and plastic sleeve. Recommended soldering temperature is within 260C for no more than 10 seconds to avoid damaging the capacitor unit.
Hole Layout on PCB	Ensure mounting hole spacing matches lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor sleeve.
