Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors when polarity is uncertain. DC electrolytic capacitors are not for AC applications. |
| Bipolar Capacitors | Suitable for pulse and polarity reverse circuits, but not 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. Exceeding rated voltage increases leakage current and may cause damage. |
| Ripple Current | Do not allow ripple current to exceed permissible limits, generally not more than 80% of rated current. Excessive ripple current causes heating, capacitance reduction, and damage. |
| 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 generally ensure longer life. |
| Temperature & Life Relationship | Life is generally doubled for every 10C reduction in operating 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. |
| Storage | For capacitors stored long-term, apply rated DC voltage gradually before use to address potential increases in leakage current and reduced 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. |
| Force on Terminals/Leads | Avoid applying excessive force to terminals and leads to prevent breakage, separation, and internal connection failure. |
| Bending Leads | When bending leads for horizontal mounting, maintain a 2mm safe distance from the capacitor body to prevent internal structural damage. |
| Cleaning | Do not use halogenated solvents (e.g., trichlorethylene, xylene, acetone) for cleaning. Recommended solvents include methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and general detergents. |
| 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 avoid stress on leads. Consider hole layout to prevent solder splashing onto the capacitor sleeve. |
