Technical Specifications

Item	Description
Polarity	DC electrolytic capacitors are polarized. Polarity is marked on the capacitor body. Reversed voltage may cause short circuit or damage. Use bipolar capacitors when polarity is not determined or unknown. DC electrolytic capacitors cannot be used for AC application.
Bipolar Capacitors	Used only in pulse circuits and polarity reverse circuits. Not applicable in pure AC or high ripple current circuits.
Voltage Rating	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 the permissible limit will cause heating, capacitance decrease, 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 operating temperatures ensure longer life.
Temperature and Life Relationship	Generally, reducing the operating temperature by 10 doubles the capacitor's life at rated temperature. The formula for calculating life is provided.
Operating Frequency	Capacitance is usually measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature.
Long-Term Storage	For capacitors stored for a long time, leakage current may increase and withstand voltage may decrease. Before use, gradually apply DC voltage up to the rated voltage.
Case Insulation	The capacitor case is not insulated from the cathode terminal. If insulation is required, it must be implemented at the capacitor's mounting point.
Terminal/Lead Force	Do not apply excessive force to terminals or leads to prevent breakage, separation, or internal connection failure.
Lead Bending	When bending leads for horizontal mounting, maintain a 2mm safe distance from the capacitor body to avoid structural damage.
Circuit Board Cleaning	Recommended cleaning solvents: Methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and general detergents. Avoid halogenated solvents like trichlorethylene, xylene, or acetone.
Soldering	Keep soldering irons away from plastic sleeves. When dipping in a solder bath, maintain temperature 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.
