Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to avoid short circuits or damage. Use bipolar capacitors for uncertain polarity. Not suitable for AC applications. |
| Bipolar Capacitors | Suitable for pulse circuits and polarity reverse circuits. Not applicable in 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 excessive ripple current. Exceeding permissible limits can cause heating, capacitance reduction, and damage. Generally, do not exceed 80% of the rated value. |
| 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 & Life Relationship | Life is inversely proportional to temperature. A 10C reduction in temperature can double the lifespan compared to 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 increasing ambient temperature. |
| Long-Term Storage | Capacitors stored for extended periods may exhibit increased leakage current and reduced withstand voltage. Before use, apply rated DC voltage gradually. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. Insulate at the mounting point if case insulation is required. |
| Terminal/Lead Force | Avoid applying excessive force to terminals and 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 prevent internal structural damage. |
| Circuit Board Cleaning | Use recommended solvents (Methanol, Isopropanol, Ethanol, etc.) for cleaning. Avoid halogenated solvents (trichlorethylene, xylene, acetone) to protect sleeve, marking, and sealing materials. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. Recommended solder bath temperature is within 260C for no more than 10 seconds to prevent damage. |
| 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 body. |
