| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to prevent 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 Usage | Do not exceed rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. |
| Ripple Current | Do not exceed permissible ripple current. Exceeding limits can cause heating, capacitance reduction, and damage. Generally, do not exceed 80% of rated current. |
| Fast Charge/Discharge Circuits | Use specially designed capacitors for circuits with rapid charge and discharge cycles to prevent damage, capacitance decrease, and heat rise. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower temperatures ensure longer life. |
| Temperature and Life Relationship | Life is approximately doubled for every 10C decrease in 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 | Capacitors stored for extended periods may have increased leakage current and reduced withstand voltage. Before use, gradually apply rated DC 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 | Do not apply excessive force to terminals and leads to prevent breakage, separation, and internal connection failure. |
| Lead Bending | When bending leads for horizontal mounting, maintain a 2mm safe spacing from the capacitor body to avoid internal structural damage. |
| Circuit Board Cleaning | Use recommended solvents (Methanol, isopropanol, ethanol, etc.). Avoid halogenated solvents (trichlorethylene, xylene, acetone) to protect the capacitor body. |
| Soldering | Maintain distance from plastic sleeves. Recommended solder bath temperature is within 260C 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. |
