Technical Specifications
The following sections detail critical usage parameters for Aluminum Electrolytic Capacitors:
| Parameter | Description |
|---|---|
| Polarity: DC electrolytic capacitors are polarized. Ensure correct polarity to prevent 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 and polarity reverse circuits, but not 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. Exceeding rated voltage increases leakage current and may damage the capacitor. | Ripple Current: Do not allow ripple current to exceed the permissible limit. Excessive ripple current causes heating, capacitance reduction, and damage. Generally, do not exceed 80% of the rated current. |
| Circuit Application: 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 & Life: Life is approximately doubled for every 10 decrease in operating temperature. Formula provided for calculation: Ls = L0 * 2^((T0-Tx)/10). (Note: Full formula not rendered due to complexity and potential ambiguity in source text). | 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 for extended periods, apply rated DC voltage gradually before use. Storage may increase leakage current and decrease withstand voltage. | Case Insulation: The capacitor case is connected to the cathode terminal via electrolyte. Insulate the case at the mounting point if line insulation is required. |
| 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 safety distance from the capacitor body to prevent internal structural damage. |
| Cleaning: Do not use halogenated solvents (e.g., trichlorethylene, xylene, acetone) for cleaning. Recommended solvents include methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and general detergents. | Soldering: Maintain distance between soldering iron and plastic sleeve. For solder bath dipping, keep temperature within 260 and duration under 10 seconds to prevent damage. |
| PCB Hole Layout: Ensure mounting hole spacing matches lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor sleeve. |
