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 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 Rating | Do not exceed the 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. Excessive ripple current causes heating, capacitance reduction, and damage. Generally, do not exceed 80% of the rated current. |
| Charge/Discharge Circuits | For circuits with rapid charge/discharge cycles, use specially designed capacitors to prevent damage, capacitance decrease, and heat rise. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower operating temperatures ensure longer life. |
| Temperature and Life Relationship | Generally, reducing operating temperature by 10 doubles the capacitor's life at rated temperature. Formula provided for calculation: Ls = L0 * 2^((T0-Tx)/10) * (I0/Ix)^m (Note: Specific values for m, T0, Tx, I0, Ix are not fully detailed in the provided text for a complete calculation example). |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature. |
| Storage | Capacitors stored for a long time may experience 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. Insulation measures are required at the mounting point if the case needs to be insulated. |
| Force on Terminals/Leads | Do not apply excessive force to terminals or 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 avoid internal structural damage. |
| Circuit Board Cleaning | Use recommended solvents like methanol, isopropanol, ethanol, isobutanol, petroleum ether, propane, and general detergents. Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect the sleeve, marking, and 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 on PCB | Ensure mounting hole spacing on the circuit board matches lead spacing to avoid stress on leads, short circuits, or circuit damage. Consider hole layout to prevent solder splashing onto the capacitor. |
