Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Polarity is marked on the capacitor body. Bipolar capacitors are available for applications with uncertain or reversing polarity. DC electrolytic capacitors are not suitable for AC applications. |
| Bipolar Capacitors | Suitable for pulse circuits and polarity reverse circuits. Not applicable for pure AC or high ripple current circuits. |
| Voltage Usage | Do not apply voltage greater than the rated voltage. Recommended working voltage is 70-80% of the rated voltage for extended lifespan. |
| Ripple Current | Do not allow ripple current to exceed the permissible limit, generally not more than 80% of the rated current. Excessive ripple current can cause heating, capacitance reduction, and damage. |
| Charge/Discharge Circuits | For circuits with rapid charge and 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 operating temperature can double the capacitor's lifespan. A formula is provided for calculating life based on temperature and ripple current. |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and Equivalent Series Resistance (ESR) increases with higher frequencies, potentially leading to increased ambient temperature. |
| Storage and Handling | Capacitors stored for extended periods 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 case insulation is necessary. |
| Terminal/Lead Force | Avoid applying excessive force to terminals and leads to prevent breakage, separation, or internal connection failure. |
| Lead Bending | When bending leads for horizontal mounting, maintain a 2mm safety distance from the capacitor body to prevent internal structural damage. |
| Circuit Board Cleaning | Use recommended solvents (Methanol, Isopropanol, Ethanol, etc.) for cleaning circuit boards. Avoid halogenated solvents (trichlorethylene, xylene, acetone) to prevent damage to the capacitor's sleeve, marking, and sealing materials. |
| Soldering | Maintain distance between the soldering iron and the plastic insulating sleeve. For solder dipping, recommended temperature is within 260C for no more than 10 seconds to prevent damage. |
| Hole Layout on PCB | Ensure mounting hole spacing matches lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor's sleeve. |
