Technical Specifications
Note: Specific part numbers and detailed specifications for individual models are not provided in the source text. The following table outlines general usage and handling guidelines relevant to technical specifications.
| Parameter | Description | Recommended Usage/Notes |
|---|---|---|
| Polarity | DC electrolytic capacitors are polarized. Polarity is marked on the capacitor body. | Ensure correct polarity to avoid short circuits or damage. Use bipolar capacitors if polarity is uncertain. DC electrolytic capacitors are not suitable for AC applications. |
| Bipolar Capacitors | Used in pulse circuits and polarity reverse circuits. | Not suitable for pure AC or high ripple current circuits. |
| Voltage | Rated voltage. | Do not exceed rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. |
| Ripple Current | Permissible ripple current. | Exceeding the permissible ripple current can cause overheating, capacitance reduction, and damage. Do not exceed 80% of the rated ripple current. |
| Charge/Discharge Cycles | Circuits with rapid charge and discharge. | Use specially designed capacitors for circuits with frequent charge/discharge cycles to prevent damage, capacitance decrease, and heat rise. |
| Operating Temperature | Temperature range affecting capacitor characteristics. | Capacitance, leakage current, and tg vary with temperature. Lower operating temperatures ensure longer life. |
| Life Expectancy | Relationship between temperature and lifespan. | Generally, a 10C reduction in operating temperature doubles the capacitor's lifespan compared to rated temperature. A formula is provided for calculation. |
| Operating Frequency | Frequency at which capacitance is measured and its effect. | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature. |
| Storage | Capacitors stored for extended periods. | Long storage can increase leakage current and decrease withstand voltage. Before use, gradually apply DC voltage up to the rated voltage. |
| Case Insulation | Insulation of the capacitor case from the cathode terminal. | The capacitor case is connected to the cathode terminal via electrolyte. If case insulation is required, implement insulation measures at the mounting point. |
| Mechanical Stress | Force applied to terminals and leads. | Avoid excessive force on terminals and leads to prevent breakage, separation, or internal connection failure. |
| Bending Leads | Bending leads for horizontal mounting. | Maintain a 2mm safe spacing between the bent lead and the capacitor body to prevent internal structural damage. |
| Cleaning | Cleaning of circuit boards after soldering. | Do not use halogenated solvents (e.g., trichlorethylene, xylene, acetone). Recommended solvents include methanol, isopropanol, ethanol, isobutanol, petroleum ether, propane, and commercial detergents. |
| Soldering | Temperature and duration during soldering. | Keep soldering irons away from plastic sleeves. Recommended solder bath temperature is within 260C for no more than 10 seconds to prevent damage. |
| Hole Layout | Hole positioning on printed circuit boards. | Ensure hole spacing matches lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor body. |
