Technical Specifications
| Item | Description |
|---|---|
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors when polarity is uncertain. Not suitable for AC applications. |
| Bipolar Capacitors Usage | Suitable for pulse circuits and polarity reverse circuits. Not applicable for pure AC or high ripple current circuits. |
| Voltage Application | 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, capacitance reduction, and damage. |
| Charge/Discharge Circuits | Use specially designed capacitors for circuits with rapid 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 | Life is extended by approximately double for every 10 reduction in operating 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 higher ambient temperatures. |
| Storage Treatment | For capacitors stored for a long time, gradually apply rated DC voltage before use to address increased leakage current and reduced 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 failure. |
| Bending Leads | Maintain a 2mm safe spacing from the capacitor body when bending leads for horizontal mounting to prevent internal structural damage. |
| Circuit Board Cleaning | Use recommended solvents (Methanol, isopropanol, ethanol, etc.). Avoid halogenated solvents (trichlorethylene, xylene, acetone) to protect the capacitor body. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. Recommended: within 260 for no more than 10 seconds when dipping in solder bath. |
| Hole Layout on PCB | Ensure mounting hole spacing matches lead spacing to avoid stress on leads. Consider hole layout to prevent solder splashing onto the capacitor. |
