Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity. Use bipolar capacitors when polarity is not fixed or uncertain. DC electrolytic capacitors cannot be used for AC applications. |
| Bipolar Capacitors | Suitable for pulse circuits and polarity reverse circuits only. Not applicable for pure AC or high ripple current circuits. |
| Voltage Rating | 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 ripple current to exceed permissible limits. Excessive ripple current causes heating, capacitance reduction, and damage. Generally, not more than 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 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. |
| 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, leakage current may increase and withstand voltage may decrease. Before use, gradually apply DC voltage up to the rated voltage. |
| 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 prevent internal structural damage. |
| Circuit Board Cleaning | Use recommended solvents like methanol, isopropanol, ethanol, etc. Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect the capacitor body. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. Recommended soldering temperature is within 260C for no more than 10 seconds to avoid 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 body. |
