Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Bipolar capacitors are used for pulse circuits and polarity reverse circuits, not for pure AC or high ripple current. |
| Voltage Usage | Do not apply voltage greater than rated voltage. Recommended working voltage is 70-80% of rated voltage. |
| Ripple Current | Do not allow excessive ripple current; generally not more than 80% of the rated current. |
| Circuit Application | Use specially designed capacitors for circuits with rapid charge and discharge cycles. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower temperatures ensure longer life. |
| Temperature & Life Relationship | Life doubles for every 10C reduction in temperature from the rated temperature. Formula provided for calculation. |
| Frequency | Capacitance decreases and tg increases with rising frequency. Measurements are typically at 100Hz or 120Hz. |
| Storage | Capacitors stored for a long time may have increased leakage current and reduced withstand voltage. Apply rated DC voltage treatment before use. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. Insulation measures are required if the case needs to be insulated. |
| Handling | Do not apply excessive force to terminals and leads. Maintain a 2mm safe spacing when bending leads for horizontal mounting. |
| Cleaning | Use recommended solvents like methanol, isopropanol, ethanol, etc. Do not use halogenated solvents. |
| Soldering | Maintain distance from plastic sleeves. Recommended temperature within 260 and duration not exceeding 10 seconds. |
| Circuit Board Design | Ensure hole spacing matches lead spacing to avoid stress. Consider hole layout to prevent solder splashing. |
