Technical Specifications
| Specification | Details |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity; reversed voltage may cause short circuit or damage. Use bipolar capacitors for uncertain polarity. Not for AC application. |
| Bipolar Capacitors | Suitable for pulse and polarity reverse circuits, not for pure AC or high ripple current. |
| Voltage Usage | Do not exceed rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. |
| Ripple Current | Do not allow excessive ripple current. Exceeding permissible limits causes heating, capacitance reduction, and damage. Generally, do not exceed 80% of rated ripple current. |
| Charge/Discharge Circuits | 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 ensure longer life. |
| Temperature & Life Relationship | Life is related to operating temperature. Reducing 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 increased ambient temperature. |
| Long-Term Storage | For capacitors stored long-term, leakage current may increase and withstand voltage may decrease. Before use, gradually apply DC voltage up to the rated voltage. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. If case insulation is required, insulation measures must be implemented at the mounting point. |
| Handling 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 | Do not use halogenated solvents (e.g., trichlorethylene, xylene, acetone) for cleaning. Recommended solvents include methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and commercial detergents. |
| Soldering | Keep soldering iron away from plastic sleeves. Recommended solder bath temperature is within 260 for no more than 10 seconds to prevent damage. |
| Hole Layout | Circuit board mounting hole spacing should match lead spacing. Improper spacing can cause stress on leads, short circuits, or damage. Consider hole layout carefully to prevent solder splashing onto the capacitor. |
