Technical Specifications
| Item | Description |
|---|---|
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors for uncertain polarity. Not for AC application. |
| Bipolar Capacitors Usage | Suitable for pulse circuits and polarity reverse circuits. Not 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 excessive ripple current. Keep ripple current at or below allowable levels, generally not more than 80% of rated current. Exceeding limits can cause heating, capacitance reduction, and damage. |
| Fast Charge/Discharge Circuits | Use specially designed capacitors for circuits with frequent charge and discharge cycles to prevent damage, capacitance decrease, and heat rise. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower temperatures generally ensure longer life. |
| Temperature and Life Relationship | Life is inversely proportional to temperature. A 10 reduction in 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 increasing ambient temperature. |
| Long-Term Storage Handling | Capacitors stored for extended periods may experience increased leakage current and reduced withstand voltage. 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 the case needs to be insulated from the circuit. |
| 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 safe spacing from the capacitor body to avoid structural damage. |
| Circuit Board Cleaning | Use recommended solvents like methanol, isopropanol, ethanol, etc. Avoid halogenated agents (trichlorethylene, xylene, acetone) to protect the capacitor body. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. For solder bath dipping, recommend temperature within 260 for no more than 10 seconds to prevent damage. |
| Hole Layout on Circuit Board | Ensure mounting hole spacing matches lead spacing to avoid stress on leads. Consider hole layout to prevent solder splashing onto the capacitor sleeve. |
