Technical Specifications
| Spec | Description |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to avoid short circuits or damage. Use bipolar capacitors when polarity is uncertain. 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 | Do not exceed the rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. Overvoltage increases leakage current and may damage the capacitor. |
| Ripple Current | Do not allow excessive ripple current. Exceeding the permissible limit causes heating, capacitance reduction, and damage. Ripple current should not exceed 80% of the rated value. |
| 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 inversely related to temperature. A 10 reduction in temperature can double the lifespan at rated temperature. Formula provided for calculation: Ls = L0 * 2^((T0-Tx)/10) * (I0/Ix)^m, where L0 is useful life at I0 and T0, Tx is actual operating temperature, Ix is actual ripple current, and m is an exponent (typically 0.2 to 0.5). |
| 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 have increased leakage current and reduced withstand voltage. Before use, gradually apply rated DC voltage. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. If insulation is required, implement it at the mounting point. |
| Force on Terminals/Leads | 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 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. Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect 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 component damage. |
| Hole Layout on PCB | Mounting hole spacing should match lead spacing. Incorrect spacing can cause stress on leads, short circuits, or damage. Consider hole layout carefully to prevent solder splashing onto the capacitor. |
