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 circuits and polarity reverse circuits. Not applicable for pure AC or high ripple current circuits. |
| Operating Voltage | Do not exceed 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 (generally not more than 80% of rated current) to prevent overheating and damage. |
| Charge/Discharge Circuits | Use specially designed capacitors for circuits with rapid, repeated charge and discharge cycles to prevent damage and premature failure. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower temperatures generally ensure longer life. |
| Temperature and Life Relationship | Capacitor life is temperature-dependent. A 10 reduction in operating 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, potentially raising ambient temperature. |
| Storage | For capacitors stored long-term, apply rated DC voltage gradually before use to restore leakage current and withstand 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 | Avoid applying excessive force to terminals and leads to prevent breakage, separation, or internal connection damage. |
| 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 cleaning solvents (e.g., Methanol, Isopropanol, Ethanol) and avoid halogenated solvents (e.g., trichlorethylene, xylene) to protect the capacitor body. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. For solder dipping, keep temperature within 260 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 to prevent solder splashing onto the capacitor body. |
