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 uncertain. DC electrolytic capacitors cannot be used for AC applications. |
| Bipolar Capacitors | Suitable for pulsating and polarity-reverse circuits only. Not applicable for pure AC or high ripple current circuits. |
| Operating Voltage | 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 damage the capacitor. |
| Ripple Current | Do not allow excessive ripple current. Exceeding permissible limits causes heating, capacitance reduction, and damage. Ripple current should not exceed 80% of the rated value. |
| Charge/Discharge Circuits | For circuits with rapid charge/discharge cycles, use specially designed capacitors to prevent damage, capacitance decrease, and heat rise. |
| Operating Temperature | Capacitor characteristics vary with temperature. Higher temperatures increase capacitance and leakage current, decreasing tg. Lower temperatures decrease capacitance and leakage current, increasing tg. Lower operating temperatures ensure longer life. |
| Temperature & Life Relationship | Life is related to operating temperature. A 10C reduction in temperature can double the lifespan at rated temperature. A formula is provided for calculation: Ls = L0 x 2^((T0-Tx)/10) where Ls is the useful life, L0 is the life at rated conditions, T0 is the maximum operating temperature, and Tx is the actual operating temperature. (Note: The provided formula in the source text appears to be incomplete or incorrectly transcribed, as it includes additional variables like Tm, I0, Ix, and Istd which are not fully defined in context for a simple life calculation based on temperature alone.) |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature. |
| Long-Term Storage | Capacitors stored for extended periods may experience increased leakage current and reduced withstand voltage. Before use, apply rated DC voltage gradually up to the rated voltage. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. If insulation is required, implement it at the capacitor's mounting point. |
| Terminal/Lead Force | Do not apply excessive force to terminals or 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 avoid structural damage. |
| Circuit Board Cleaning | Use recommended solvents like methanol, isopropanol, ethanol, isobutanol, petroleum ether, propane, and general detergents. Avoid halogenated solvents (e.g., trichlorethylene, xylene, acetone) to prevent damage to the sleeve, marking, and sealing materials. |
| Soldering | Maintain distance between the soldering iron and the plastic insulating sleeve. When dipping in a solder bath, recommended temperature is within 260C for no more than 10 seconds to prevent damage to the capacitor element. |
| Hole Layout on PCB | Ensure mounting hole spacing on the circuit board matches the lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the plastic sleeve. |
