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 circuits and polarity reverse circuits. Not applicable for pure AC or high ripple current circuits. |
| Voltage Rating | 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 value) to prevent overheating and damage. |
| Fast Charge/Discharge Circuits | Use specially designed capacitors for circuits with frequent charge/discharge cycles to prevent damage and premature failure. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower temperatures generally ensure longer life. |
| Temperature and Life Relationship | Life is approximately doubled for every 10 reduction in operating temperature below 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, potentially increasing ambient temperature. |
| Storage and Usage | For capacitors stored long-term, apply rated DC voltage gradually before use to restore performance and 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. |
| Force on Terminals/Leads | Avoid applying excessive force to terminals and leads to prevent breakage, separation, or internal connection failure. |
| Lead Bending | When bending leads for horizontal mounting, maintain a 2mm safe spacing from the capacitor body to prevent internal structural damage. |
| Circuit Board Cleaning | Use recommended solvents (Methanol, Isopropanol, Ethanol, etc.) for cleaning. Avoid halogenated agents or solvents like trichlorethylene, xylene, or acetone to protect the capacitor body. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. Recommended solder bath temperature is within 260 for no more than 10 seconds to prevent component damage. |
| Hole Layout on PCB | Ensure hole spacing on the circuit board matches lead spacing to avoid stress on leads. Consider hole layout to prevent solder splashing onto the capacitor body. |
