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 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 exceed permissible ripple current. Flowing excessive ripple current can cause heating, capacitance reduction, and damage. Generally, not more than 80% of rated current. |
| Charge/Discharge Circuits | For circuits with frequent 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 vs. Life | Life is related to operating temperature. Reducing temperature by 10 can double the life at rated temperature. Formula provided for calculation. |
| Operating Frequency | Capacitance measured at 100Hz or 120Hz. Capacitance decreases and tg increases with rising frequency, potentially increasing ambient temperature. |
| Long-Term Storage | For capacitors stored for a long time, 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 safety distance from the capacitor body to prevent internal structural damage. |
| Circuit Board Cleaning | Use recommended solvents like Methanol, Isopropanol, Ethanol, etc. Do not use halogenated solvents (trichlorethylene, xylene, acetone) to avoid damaging the sleeve, marking, or sealing materials. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. Recommended solder bath temperature is within 260 for no more than 10 seconds to prevent component 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. |
