Technical Specifications
| Item | Description |
|---|---|
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors if polarity is uncertain. Not suitable 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. |
| Working Voltage | Do not exceed rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. |
| Ripple Current | Do not allow excessive ripple current. Exceeding permissible limits 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, capacitance decrease, and heat rise. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower temperatures generally ensure longer life. |
| Temperature and Life Relationship | Life is approximately doubled for every 10 decrease in operating temperature from the 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. |
| Long-Term Storage Handling | For capacitors stored for extended periods, gradually apply rated DC voltage before use to address potential increases in leakage current and reduced 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 | Avoid applying 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. |
| Cleaning After Soldering | Use recommended solvents like methanol, isopropanol, ethanol, etc. Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect the capacitor body. |
| Soldering Temperature and Duration | Maintain a distance between the soldering iron and the plastic sleeve. Recommended soldering temperature is within 260 for no more than 10 seconds. |
| PCB Hole Layout | Ensure mounting hole spacing on PCBs matches lead spacing to avoid stress on leads. Consider hole layout to prevent solder splashing onto the capacitor body. |
