Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Polarity is marked on the capacitor body. Reversed voltage may cause short circuit or damage. Use bipolar capacitors when polarity is not determined or unknown. DC electrolytic capacitors cannot be used for AC applications. |
| Bipolar Capacitors | Used only in pulse circuits and polarity reverse circuits; not applicable in pure AC or high ripple current circuits. |
| Voltage Usage | Do not apply voltage greater than rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. |
| Ripple Current | Do not allow excessive ripple current. Exceeding the permissible limit causes heating, capacitance reduction, and damage. Ripple current should not exceed 80% of the rated value. |
| Rapid Charge/Discharge Circuits | Use specially designed capacitors for circuits with frequent 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 Relationship | Life is approximately doubled for every 10C reduction in temperature from the rated temperature. Formula provided for calculation: Ls = L0 x 2^((T0-Tx)/10) where L0 is useful life at rated ripple current I0 and max operating temperature T0; Lx is actual ripple current; Tx is actual operating temperature. |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to ambient temperature rise. |
| Storage and Usage | For capacitors stored for a long time, leakage current may increase and withstand voltage may decrease. 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 must be taken at the mounting point if case insulation is required. |
| Mechanical Force | Do not apply excessive force to terminals and leads to prevent breakage, separation, or internal connection failure. |
| Lead Bending | When bending leads for horizontal mounting, maintain a 2mm safe spacing from the capacitor body to avoid internal structural damage. |
| Circuit Board 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 | Keep soldering irons away from plastic sleeves. Recommended soldering temperature is within 260C for no more than 10 seconds in a solder bath to prevent damage. |
| Hole Layout | Ensure mounting hole spacing on circuit boards matches lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor body. |
