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 fixed or unknown. DC electrolytic capacitors are not for AC applications. |
| Bipolar Capacitors | Used only in pulse circuits and polarity reverse circuits. Not applicable in 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 the permissible limit 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. Lower temperatures ensure longer life. |
| Temperature & Life Relationship | Generally, reducing operating temperature by 10C doubles the lifespan at rated temperature. Formula provided for calculation: Ls = L0 * 2^((T0-Tx)/10) * (I0/Ix)^m, where L0 is useful life at max temp T0 with ripple I0, Tx is actual operating temp, Ix is actual ripple current, and m is a coefficient (5C for Tm). |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature. |
| Storage | Capacitors stored for a long time may experience increased leakage current and reduced withstand voltage. Before use, apply rated DC voltage gradually. |
| Case Insulation | The capacitor case is connected to the cathode terminal via the electrolyte. If insulation is required, it must be implemented 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 internal structural damage. |
| Circuit Board Cleaning | Clean circuit boards with recommended solvents (Methanol, isopropanol, ethanol, isobutanol, petroleum ether, propane, or commercial detergents). Avoid halogenated solvents (trichlorethylene, xylene, acetone) to protect the sleeve, marking, and sealing materials. |
| Soldering | Keep soldering irons away from plastic sleeves. Recommended solder bath temperature is within 260C for no more than 10 seconds to prevent damage. |
| Hole Layout | Ensure mounting hole spacing on circuit boards matches lead spacing to avoid stress on leads. Solder splashing onto the plastic sleeve can cause damage; consider hole layout carefully. |
