Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to avoid short circuits or damage. Use bipolar capacitors when polarity is uncertain. DC electrolytic capacitors are not for AC applications. Bipolar capacitors are for pulsed or polarity-reversing circuits, not pure AC or high ripple. |
| 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. Exceeding limits causes heating, capacitance reduction, and damage. Generally, do not exceed 80% of rated current. |
| Charge/Discharge | 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 & Life Relationship | Life is related to operating temperature. Reducing temperature by 10 can double the life compared to 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 an exponent. |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to higher ambient temperature. |
| Storage | For capacitors stored long-term, apply rated DC voltage treatment before use. Long storage may increase leakage current and decrease withstand voltage. Gradually apply DC voltage to rated voltage before use. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. If case insulation is required, implement insulation at the mounting point. |
| Force on Terminals/Leads | 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 internal structural damage. |
| Circuit Board Cleaning | Use recommended cleaning solvents like methanol, isopropanol, ethanol, isobutanol, petroleum ether, propane, or commercial detergents. Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect the sleeve, marking, and sealing materials. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. For solder dipping, recommend temperature within 260 and duration not exceeding 10 seconds to prevent damage. |
| Hole Layout on PCB | Ensure mounting hole spacing matches lead spacing. Incorrect spacing can cause stress on leads, short circuits, circuit damage, and increased leakage current. Consider hole layout carefully to prevent solder splashing onto the sleeve. |
