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 for AC applications. |
| Bipolar Capacitors | Suitable for pulse and polarity reverse circuits only. Not for pure AC or high ripple current circuits. |
| Voltage | 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 causes heating, capacitance reduction, and damage. Generally not more than 80% of rated current. |
| Charge/Discharge Circuits | Use specially designed capacitors for circuits with rapid charge/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 | Life is inversely proportional to temperature. A 10C reduction in temperature typically doubles the lifespan at rated temperature. Formula provided for calculation. |
| Operating Frequency | Capacitance is usually measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased 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 must be applied at the mounting point if required. |
| Terminal Force | Do not apply excessive force to terminals or leads to prevent breakage, separation, or internal connection failure. |
| Lead Bending | When bending leads for horizontal mounting, maintain a 2mm safety distance from the capacitor body to avoid internal structural damage. |
| Cleaning | Use recommended solvents (Methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, detergents) for cleaning circuit boards. Avoid halogenated solvents (trichlorethylene, xylene, acetone). |
| Soldering | Maintain distance between soldering iron and plastic sleeve. Recommended soldering temperature is within 260C for no more than 10 seconds to prevent damage. |
| Hole Layout | Ensure circuit board hole spacing matches lead spacing to avoid stress on leads. Consider hole layout to prevent solder splashing onto the capacitor sleeve. |
