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 and polarity reverse circuits. Not applicable for pure AC or high ripple current circuits. |
| Voltage | 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, generally not exceeding 80% of rated current, to prevent overheating, capacitance reduction, and damage. |
| Charge/Discharge Circuits | Use specially designed capacitors for circuits with frequent charge and discharge cycles to prevent damage, capacitance decrease, and heat rise. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower operating temperatures ensure longer life. |
| Temperature vs. Life | Life is inversely proportional to temperature. Reducing temperature by 10C can double the lifespan. Formula provided for calculation. |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient 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 | The capacitor case is not insulated from the cathode terminal. Insulation must be provided at the mounting point if required. |
| Mechanical Stress | Avoid applying excessive force to terminals and 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 prevent internal structural damage. |
| Cleaning | Do not use halogenated solvents (e.g., trichlorethylene, xylene, acetone) for cleaning. Recommended solvents include methanol, isopropanol, ethanol, isobutanol, petroleum ether, propane, and commercial detergents. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. For solder bath dipping, keep temperature within 260C and duration under 10 seconds to prevent damage. |
| Hole Layout | Ensure mounting hole spacing on circuit boards matches lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor. |
