Technical Specifications
| Specification | 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 and polarity reverse circuits only. Not applicable in 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 allow excessive ripple current. Exceeding permissible limits can cause heating, capacitance reduction, and damage. Generally, ripple current should not exceed 80% of the rated value. |
| 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 temperatures generally ensure longer life. |
| Temperature and Life Relationship | Life is inversely proportional to temperature. A 10C reduction in temperature can double the lifespan at rated temperature. Formula provided for calculation: Ls = L0 * 2^((T0-Tx)/10) * (I0/Ix)^m, where L0 is useful life at I0 and T0, Tx is actual operating temperature, Ix is actual ripple current, and m is a constant (typically 2 for aluminum electrolytic capacitors). |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, potentially increasing ambient temperature. |
| Storage | For capacitors stored long-term, apply rated DC voltage treatment before use. This addresses potential increases in 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. |
| Force on Terminals/Leads | Avoid applying excessive force to terminals and 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 prevent internal structural damage. |
| Cleaning After Soldering | Use recommended cleaning solvents such as methanol, isopropanol, ethanol, isobutanol, petroleum ether, propane, and commercial detergents. Avoid halogens agents or solvents like trichlorethylene, xylene, or acetone to protect the sleeve, marking, and sealing materials. |
| Soldering Conditions | Keep soldering irons away from plastic sleeves. Recommended solder bath temperature is within 260C for no more than 10 seconds to avoid damaging the capacitor unit. |
| Circuit Board Hole Layout | Ensure mounting hole spacing matches lead spacing to avoid stress on leads, short circuits, or circuit damage. Consider hole layout carefully to prevent solder splashing onto the capacitor body. |
