Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors for undetermined or unknown 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 rated voltage for extended life. |
| Ripple Current | Do not allow ripple current to exceed permissible limits. Excessive ripple current causes heat, capacitance reduction, and damage. Generally, do not exceed 80% of the rated ripple current. |
| Circuit Application | 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 | Capacitor life is related to operating temperature. Reducing the temperature by 10 can double the life at rated temperature. Formula provided for calculation. |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to higher ambient temperature. |
| Storage and Usage | For capacitors stored for a long time, gradually apply rated DC voltage 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 must be taken at the mounting point if case insulation is required. |
| Mechanical Force | Do not apply excessive force to terminals or leads to prevent breakage, separation, or internal connection failure. |
| Lead Bending | When bending leads for horizontal mounting, maintain a 2mm safe spacing from the capacitor body to prevent internal structural damage. |
| Circuit Board Cleaning | Use recommended solvents (Methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, commercial detergents) for cleaning after soldering. Avoid halogenated solvents (trichlorethylene, xylene, acetone) to protect the capacitor body. |
| Soldering | Maintain a distance between the soldering iron and the plastic sleeve. Recommended soldering temperature is within 260 for no more than 10 seconds to avoid damaging the capacitor unit. |
| Hole Layout | Ensure mounting hole spacing on the circuit board matches lead spacing to prevent stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor body during assembly. |
