Usage Guidelines for Aluminum Electrolytic Capacitors
To ensure optimal performance and extend the lifespan of Aluminum Electrolytic Capacitors, please carefully read and adhere to the following guidelines before use.
| No. | Guideline | Description |
| 1 | Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity is observed as marked on the capacitor body. Reversed voltage can cause short circuits or damage. Use bipolar capacitors for uncertain or unfixed polarity. DC electrolytic capacitors are not suitable for AC applications. |
| 2 | Bipolar Capacitors | Suitable only for pulse circuits and polarity reverse circuits. Not applicable for pure AC or high ripple current circuits. |
| 3 | Operating Voltage | Do not apply voltage greater than the rated voltage. Recommended working voltage is 70-80% of the rated voltage for extended capacitor life. Exceeding rated voltage increases leakage current and may damage the capacitor. |
| 4 | Ripple Current | Do not allow excessive ripple current to pass through the capacitor. Exceeding the permissible ripple current can cause heating, reduced capacitance, and damage. Ripple current should generally not exceed 80% of the rated value. |
| 5 | Charge/Discharge Circuits | For circuits with rapid charge and discharge cycles, use specially designed capacitors. Standard capacitors may be damaged, leading to reduced capacitance and heat rise. |
| 6 | Operating Temperature Range | Capacitor characteristics vary with temperature. Lower operating temperatures ensure longer life. At higher temperatures, capacitance and leakage current increase, while tg decreases. At lower temperatures, capacitance and leakage current decrease, while tg increases. |
| 7 | Relationship between Temperature and Life | Capacitor life is temperature-dependent. Generally, reducing the operating temperature by 10 doubles the lifespan compared to rated temperature. The formula for calculating life is provided (see original document for formula details). |
| 8 | Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature. |
| 9 | Long-Term Storage Treatment | For capacitors stored for extended periods, leakage current may increase and withstand voltage may decrease. Before use, gradually apply DC voltage up to the rated voltage. |
| 10 | Case Insulation | The capacitor case is not insulated from the cathode terminal. If case insulation is required, implement insulation measures at the capacitor's mounting point. |
| 11 | Force on Terminals/Leads | Do not apply excessive force to terminals and leads to prevent breakage, separation, or internal connection failure. |
| 12 | Bending Leads | When bending leads for horizontal mounting, maintain a 2mm safe distance from the capacitor body to prevent internal structural damage. |
| 13 | Circuit Board Cleaning | When cleaning circuit boards after soldering, avoid using halogenated solvents (e.g., trichlorethylene, xylene, acetone) that can damage the capacitor's sleeve, marking, or sealing materials. Recommended cleaning solvents include methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and general detergents. |
| 14 | Soldering Temperature and Duration | Keep soldering irons away from the plastic insulated sleeves. When dipping in a solder bath, the temperature should not exceed 260, and the duration should not exceed 10 seconds to prevent damage. |
| 15 | Hole Layout on Circuit Board | Ensure mounting hole spacing on the circuit board matches the lead spacing of the capacitor to avoid stress on leads. Carefully consider hole layout to prevent solder splashing onto the capacitor's sleeve. |
