Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. The polarity is marked on the body of the capacitor. Use bipolar capacitors when the polarity is not determined or unknown. DC electrolytic capacitors cannot be used for AC application. |
| Bipolar Capacitors | Used only in pulse circuits as well as polarity reverse circuits, but 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 to 80 percent of rated voltage for extended life. |
| Ripple Current | Do not allow excessive ripple current through the capacitor. Ripple current should generally not exceed 80% of the rated current. Excessive ripple current can cause heating, capacitance reduction, and damage. |
| Charge/Discharge Circuits | For circuits with rapid charge and discharge cycles, use specially designed capacitors to prevent damage, capacitance decrease, and heat rise. |
| Operating Temperature | Capacitor characteristics vary with temperature. Usage at lower temperatures ensures longer life. |
| Temperature and Life Relationship | Generally, a 10 reduction in operating temperature doubles the capacitor's lifespan at rated temperature. The formula for calculating useful life is provided. |
| 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 for a long time, apply rated DC voltage gradually before use. Long storage may increase leakage current and decrease withstand voltage. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. If insulation is required, it must be implemented at the capacitor's mounting point. |
| Force on Terminals/Leads | Do not apply excessive force to terminals or leads to prevent breakage, separation, or internal connection failure. |
| Lead Bending | When bending leads for horizontal mounting, maintain a 2mm safe spacing from the capacitor body to avoid structural damage. |
| Circuit Board Cleaning | Recommended cleaning solvents: Methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and general detergents. Avoid halogenated solvents like trichlorethylene, xylene, or acetone. |
| Soldering | Maintain distance between the soldering iron and the plastic sleeve. For solder bath dipping, recommendable temperature is within 260 for no more than 10 seconds to prevent component damage. |
| Hole Layout | Ensure circuit board hole spacing matches lead spacing to avoid stress on leads. Consider hole layout to prevent solder splashing onto the capacitor body. |
