Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to avoid short circuits or damage. Use bipolar capacitors when polarity is uncertain. DC electrolytic capacitors are not suitable for AC applications. |
| Bipolar Capacitors | Suitable for pulse circuits and polarity reverse circuits. Not applicable 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. |
| Ripple Current | Do not allow excessive ripple current. Exceeding permissible limits can cause overheating, reduced capacitance, and damage. Ripple current should generally not exceed 80% of the rated value. |
| Charge/Discharge Circuits | For circuits with frequent 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 & Life Relationship | Life is inversely proportional to temperature. Reducing operating temperature by 10C can double the lifespan at rated temperature. Formula provided for calculation: Ls = L0 * 2^((T0-Tx)/10) where L0 is useful life at max temp T0, Tx is actual operating temp, and Ls is calculated life. (Note: The provided formula in the source text appears incomplete or misformatted, but the general principle is stated.) |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, potentially raising ambient temperature. |
| Long-Term 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, or 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. |
| Circuit Board Cleaning | Use recommended solvents (Methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, commercial detergents) for cleaning circuit boards. Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect the capacitor body. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. For solder dipping, recommendable temperature is within 260C for no more than 10 seconds to prevent component damage. |
| Hole Layout on PCB | Ensure mounting hole spacing matches lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor body. |
