Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Bipolar capacitors are for pulse and polarity reverse circuits, not pure AC or high ripple. |
| Voltage | Do not apply voltage greater than rated voltage. Recommended working voltage is 70-80% of rated voltage. |
| Ripple Current | Do not allow excessive ripple current. Generally, not more than 80% of rated current. Exceeding limits causes heating, capacitance reduction, and damage. |
| Frequency | Capacitance measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequency, leading to temperature rise. |
| Temperature | Characteristics vary with temperature. Lower temperatures ensure longer life. Life doubles for every 10 decrease in temperature. |
| Storage | For capacitors stored long-term, apply rated DC voltage gradually before use. Storage may increase leakage current and decrease withstand voltage. |
| Case Insulation | Capacitor case is not insulated from the cathode terminal. Insulation must be applied at the mounting point if required. |
| Handling | Do not apply excessive force to terminals or leads to prevent breakage 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. |
| Cleaning | Do not use halogenated solvents (e.g., trichlorethylene, xylene, acetone) for cleaning circuit boards. Recommended solvents: methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and commercial detergents. |
| Soldering | Keep soldering irons away from plastic sleeves. Recommended solder bath temperature: within 260 for no more than 10 seconds. |
| PCB Layout | Ensure mounting hole spacing matches lead spacing to avoid stress on leads. Consider hole layout to prevent solder splashing onto the capacitor. |
