Technical Specifications
| 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 and polarity reverse circuits only. Not applicable in 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 overheating, capacitance reduction, and damage. Generally, do not exceed 80% of rated current. |
| 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 | Life is related to operating temperature. A 10C reduction in temperature can double the lifespan at rated temperature. Formula provided for life calculation. |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, potentially increasing ambient temperature. |
| Storage | For capacitors stored long-term, apply rated DC voltage gradually before use. Storage may increase leakage current and decrease 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 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 (Methanol, Isopropanol, Ethanol, etc.) for cleaning circuit boards after soldering. Avoid halogenated solvents (trichlorethylene, xylene, acetone) to protect the capacitor body. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. Recommended soldering temperature is within 260C for no more than 10 seconds to avoid component damage. |
| Hole Layout | Ensure mounting hole spacing on circuit boards matches lead spacing to prevent stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor body. |
