Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors if polarity is uncertain. 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. Generally, do not exceed 80% of rated current. |
| 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. Lower temperatures generally ensure longer life. |
| Temperature and Life Relationship | Life is inversely proportional to temperature. A 10 reduction in temperature can double the lifespan at rated temperature. Formula provided for calculation: $L_x = L_0 \times 2^{\frac{T_0 - T_x}{\Delta T_m}}$ where $L_0$ is useful life at max operating temp $T_0$ with ripple current $I_{std}$, $T_x$ is actual operating temp, $\Delta T_m$ is 5, $I_x$ is actual ripple current, and $I_0$ is rated ripple current. |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, potentially raising ambient temperature. |
| Storage | Capacitors stored for long periods may experience increased leakage current and reduced withstand voltage. Before use, apply rated DC voltage gradually. |
| 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. |
| 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 spacing from the capacitor body to avoid internal structural damage. |
| Circuit Board Cleaning | Clean circuit boards with recommended solvents (Methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, commercial detergents). Avoid halogenated solvents (trichlorethylene, xylene, acetone) to protect the capacitor body. |
| Soldering | Maintain distance from plastic sleeves. When dipping in solder bath, recommendable temperature is within 260 for no more than 10 seconds to avoid damage. |
| Hole Layout | Ensure mounting hole spacing matches lead spacing on circuit boards to prevent stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor. |
