Technical Specifications
| Item | Description | Key Considerations |
| 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 application. | Ensure correct polarity marking. Use bipolar for uncertain polarity. |
| Bipolar Capacitors | Suitable for pulse and polarity reverse circuits. Not for pure AC or high ripple current circuits. | Limited application scope. |
| Operating 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. Exceeding permissible limits causes heating, reduced capacitance, and damage. Generally not more than 80% of rated current. | Ripple current causes heat; limit to prevent damage. |
| Charge/Discharge Circuits | Use specially designed capacitors for circuits with rapid charge/discharge cycles to prevent damage, capacitance decrease, and heat rise. | Requires specialized capacitor design. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower temperatures ensure longer life. | Temperature affects capacitance, leakage current, and tg. |
| Temperature & Life Relationship | Life doubles for every 10 decrease in temperature from rated temperature. Formula provided for calculation. | Life is inversely proportional to temperature. |
| Operating Frequency | Capacitance measured at 100Hz/120Hz. Capacitance decreases and tg increases with higher frequencies, causing temperature rise. | Frequency affects capacitance and dielectric loss. |
| Long-Term Storage | Capacitors stored for long periods may have increased leakage current and reduced withstand voltage. Treat with rated DC voltage before use. | Recondition before use after prolonged storage. |
| Case Insulation | Capacitor case is connected to the cathode terminal via electrolyte. Insulate at mounting point if case insulation is required. | Case is not inherently insulated. |
| Terminal/Lead Force | Do not apply excessive force to terminals or leads to prevent breakage, separation, or internal connection failure. | Handle with care to avoid mechanical stress. |
| Bending Leads | Maintain a 2mm safe spacing between bent leads and the capacitor body to prevent internal structural damage. | Proper bending technique is crucial. |
| Circuit Board Cleaning | Use recommended solvents (methanol, isopropanol, ethanol, etc.). Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect sleeve, marking, and sealing materials. | Use appropriate cleaning agents. |
| Soldering | Maintain distance between soldering iron and plastic sleeve. Recommended: within 260 for no more than 10 seconds to avoid component damage. | Control temperature and duration during soldering. |
| Hole Layout on PCB | Hole spacing should match lead spacing. Incorrect spacing can cause stress on leads, short circuits, or damage. Consider solder splashing onto the sleeve. | Proper PCB layout is essential for reliable mounting. |
