Technical Specifications

Item	Description
Polarity	DC electrolytic capacitors are polarized. Ensure correct polarity to avoid short circuits or damage. Use bipolar capacitors if polarity is not fixed or uncertain. DC electrolytic capacitors are not suitable 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 exceed the rated voltage. Recommended working voltage is 70-80% of the rated voltage for extended lifespan.
Ripple Current	Do not allow excessive ripple current, which can cause heating, capacitance reduction, and damage. Ripple current should generally not exceed 80% of the rated value.
Charge/Discharge Circuits	For circuits with rapid charge/discharge cycles, use specially designed capacitors to prevent damage and premature failure.
Operating Temperature	Capacitor characteristics vary with temperature. Lower temperatures generally ensure longer life.
Temperature and Life Relationship	Capacitor life is temperature-dependent. Reducing operating temperature by 10 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 tan (dissipation factor) increases with higher frequencies, leading to increased ambient temperature.
Storage and Handling	For capacitors stored long-term, apply rated DC voltage gradually before use to address potential increases in leakage current and reduced withstand voltage.
Case Insulation	The capacitor case is connected to the cathode terminal via the electrolyte. If case insulation is required, implement insulation measures at the mounting point.
Terminal/Lead Force	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 safe distance from the capacitor body to prevent internal structural damage.
Circuit Board Cleaning	Use recommended cleaning solvents like methanol, isopropanol, ethanol, etc. Avoid halogenated solvents (e.g., trichlorethylene, xylene, acetone) to protect the capacitor's sleeve, marking, and sealing materials.
Soldering	Maintain distance between the soldering iron and the plastic insulating sleeve. For solder dipping, recommended temperature is within 260 for no more than 10 seconds to prevent damage.
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's sleeve.
