Technical Specifications
| Parameter | Description | Notes |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors if polarity is uncertain. Not for AC applications. | Marked on capacitor body. |
| Bipolar Capacitors | Suitable for pulse and polarity reverse circuits. Not for pure AC or high ripple current circuits. | |
| Voltage | Do not exceed rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. | Exceeding rated voltage increases leakage current and may cause damage. |
| Ripple Current | Do not allow excessive ripple current. Generally, do not exceed 80% of rated current. | Excessive ripple current causes heating, capacitance reduction, and damage. |
| Charge/Discharge Cycles | Use specially designed capacitors for circuits with rapid charge/discharge cycles. | Rapid cycles can shorten lifespan due to capacitance decrease and heat rise. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower temperatures ensure longer life. | Capacitance and leakage current change with temperature. |
| Temperature & Life Relationship | Life is approximately doubled for every 10C reduction in temperature from the rated temperature. Formula provided for calculation. | L0: Useful life at rated ripple current Istd and max temp T0. T0: Max Operating Temp. Tx: Actual Operating Temp. Ix: Actual Ripple Current. I0: Rated Ripple Current. Tm: 5. |
| Operating Frequency | Capacitance measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to higher ambient temperature. | Be aware of frequency effects on performance. |
| Storage | For capacitors stored long-term, apply rated DC voltage gradually before use. | Long storage may increase leakage current and decrease withstand voltage. |
| Case Insulation | Capacitor case is not insulated from the cathode terminal. Insulation measures are required if the case must be insulated from the circuit. | Case connects to cathode via electrolyte. |
| Mechanical Stress | Do not apply excessive force to terminals and leads to prevent breakage or internal connection failure. | |
| Bending Leads | Maintain a 2mm safe spacing from the capacitor body when bending leads for horizontal mounting to avoid internal structural damage. | |
| Cleaning | Use recommended solvents (Methanol, Isopropanol, Ethanol, etc.). Do not use halogenated solvents (trichlorethylene, xylene, acetone) to protect sleeve, marking, and sealing materials. | Clean circuit boards to remove flux. |
| Soldering | Maintain distance from plastic sleeve. Recommended temperature: within 260C, duration: not exceeding 10 seconds. | Avoid damage to the capacitor unit. |
| Hole Layout | Mounting hole spacing should match lead spacing. Incorrect spacing can cause stress, short circuits, or damage. Consider hole layout to prevent solder splashing onto the sleeve. | Ensure proper mounting to avoid electrical and physical damage. |
