Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to avoid short circuits or damage. Use bipolar capacitors when polarity is uncertain. Not suitable for AC applications. |
| Bipolar Capacitors | Suitable for pulse circuits and polarity reverse circuits. Not applicable in 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. Exceeding rated voltage increases leakage current and may damage the capacitor. |
| Ripple Current | Do not allow excessive ripple current. Exceeding permissible limits causes heating, reduced capacitance, and potential 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 ensure longer life. |
| Temperature & Life Relationship | Life is inversely proportional to temperature. Reducing operating temperature by 10C 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 tg increases with higher frequencies, leading to increased ambient temperature. |
| Long-Term Storage | Capacitors stored for extended periods may experience increased leakage current and reduced withstand voltage. Before use, gradually apply DC voltage up to the rated voltage. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. Insulation measures are required at the mounting point if the case needs to be insulated from the circuit. |
| Terminal/Lead Force | Do not apply excessive force to terminals or 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 avoid internal structural damage. |
| Circuit Board Cleaning | Use recommended solvents like methanol, isopropanol, ethanol, etc. Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect the capacitor body, marking, and sealing materials. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. Recommended solder bath temperature is within 260C for no more than 10 seconds to prevent component damage. |
| Hole Layout | Circuit board hole spacing should match lead spacing. Incorrect spacing can cause stress on leads, short circuits, or damage. Consider hole layout carefully to prevent solder splashing onto the capacitor. |
