Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Polarity is marked on the capacitor body. Reverse voltage application 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 | Suitable for 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 permissible limits can cause heating, capacitance reduction, and damage. Ripple current should generally 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 generally ensure longer life. |
| Temperature and Life Relationship | Life is inversely proportional to temperature. A 10C reduction in temperature can double the lifespan at rated temperature. Formula provided for calculation: Ls = L0 * 2^((T0-Tx)/10) * sqrt((I0/Ix)*(Tm-Tx)/(Tm-T0)) where L0 is useful life at ripple current I0 and max temp T0; Tx is actual operating temp; Ix is actual ripple current; Tm is max temp for ripple current I0. |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature. |
| Storage Treatment | For capacitors stored long-term, apply rated DC voltage gradually before use. This addresses potential increases in leakage current and decreased withstand voltage. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. Insulation must be applied at the capacitor's mounting point if case insulation is required. |
| 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. |
| Cleaning Circuit Boards | Use recommended solvents like methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and general detergents. Avoid halogenated solvents (trichloroethylene, xylene, acetone) to prevent damage to the sleeve, marking, and sealing materials. |
| Soldering | Maintain distance between the soldering iron and the plastic insulated sleeve. For solder bath dipping, recommend temperatures within 260C for no more than 10 seconds to prevent damage. |
| Hole Layout on PCB | Ensure mounting hole spacing on the circuit board matches lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the vinyl sleeve. |
