Technical Specifications

Item	Description
Polarity	DC electrolytic capacitors are polarized. Ensure correct polarity to avoid short circuits or damage. Use bipolar capacitors for uncertain polarity. Not suitable for AC applications.
Bipolar Capacitors	Suitable for pulse 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.
Ripple Current	Do not allow ripple current to exceed permissible limits (generally not more than 80% of rated current) to prevent overheating, capacitance reduction, and damage.
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.
Temperature vs. Life	Life is inversely proportional to temperature. A 10 reduction in temperature can double the 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	For capacitors stored long-term, apply rated DC voltage gradually before use to address increased leakage current and reduced withstand voltage.
Case Insulation	The capacitor case is not insulated from the cathode terminal. Implement insulation measures at the mounting point if case insulation is required.
Force on Terminals/Leads	Avoid applying excessive force to terminals and leads to prevent breakage, separation, and 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	Do not use halogenated solvents (e.g., trichlorethylene, xylene, acetone) for cleaning. Recommended solvents include methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and commercial detergents.
Soldering	Maintain distance between soldering iron and plastic sleeve. For solder bath dipping, keep temperature within 260 and duration under 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 to prevent solder splashing onto the capacitor body.
