Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Polarity is marked on the capacitor body. Reversed voltage may cause short circuit or damage. Use bipolar capacitors if polarity is undetermined. DC electrolytic capacitors are not for AC application. |
| Bipolar Capacitors Usage | Suitable only for pulse circuits and polarity reverse circuits. Not applicable in pure AC or high ripple current circuits. |
| Voltage Application | Do not apply voltage greater than rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. |
| Ripple Current | Do not allow excessive ripple current. Exceeding permissible ripple current causes heating, capacitance reduction, and damage. Ripple current should generally not exceed 80% of rated value. |
| Fast Charge/Discharge Circuits | Use specially designed capacitors for circuits with rapid charge and discharge cycles to prevent damage, capacitance decrease, and heat rise. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower temperatures ensure longer life. |
| Temperature and Life Relationship | Life is inversely proportional to temperature. Reducing operating temperature by 10 can double the lifespan. Formula provided for calculation. |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature. |
| Long-Term Storage | 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 | 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 (Methanol, isopropanol, ethanol, etc.). Do not use halogenated or similar solvents (trichlorethylene, xylene, acetone) to avoid damaging the capacitor body. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. Recommended solder bath temperature is within 260 for no more than 10 seconds to prevent damage. |
| Hole Layout on PCB | Mounting hole spacing should match lead spacing. Improper spacing can cause stress on leads, short circuits, or circuit damage. Consider hole layout carefully to prevent solder splashing onto the capacitor body. |
