Technical Specifications
The following guidelines detail crucial parameters and usage recommendations for Aluminum Electrolytic Capacitors:
| Guideline Number | Description | Key Considerations |
|---|---|---|
| 1 | Polarity of DC Electrolytic Capacitors | Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors if polarity is uncertain. Not suitable for AC applications. |
| 2 | Bipolar Capacitors Usage | Suitable for pulse and polarity reverse circuits. Not for pure AC or high ripple current circuits. |
| 3 | Operating Voltage | Do not exceed rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. |
| 4 | Ripple Current | Do not exceed permissible ripple current limits to prevent overheating, capacitance reduction, and damage. Generally, not more than 80% of rated current. |
| 5 | Charge and Discharge Circuits | Use specially designed capacitors for circuits with frequent charge/discharge cycles to prevent damage and premature failure. |
| 6 | Operating Temperature Range | Capacitor characteristics vary with temperature. Lower temperatures generally ensure longer life. |
| 7 | Relationship Between Temperature and Life | Life is approximately doubled for every 10 decrease in operating temperature from the maximum rated temperature. Formula provided for calculation. |
| 8 | Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and Equivalent Series Resistance (ESR) increases with higher frequencies, potentially increasing ambient temperature. |
| 9 | Long-Term Storage Treatment | Capacitors stored for extended periods may exhibit increased leakage current and reduced withstand voltage. Apply rated DC voltage gradually before use. |
| 10 | Case Insulation | The capacitor case is not insulated from the cathode terminal. Insulation measures are required at the mounting point if case insulation is necessary. |
| 11 | Force on Terminals and Leads | Avoid applying excessive force to terminals and leads to prevent breakage, separation, and internal connection damage. |
| 12 | Bending Leads (Horizontal Mount) | Maintain a 2mm safe spacing between the bend and the capacitor body to prevent internal structural damage. |
| 13 | Circuit Board Cleaning | Use recommended solvents (e.g., methanol, isopropanol, ethanol) and avoid halogenated or similar solvents (e.g., trichlorethylene, xylene, acetone) to protect the capacitor body, marking, and sealing materials. |
| 14 | Soldering Temperature and Duration | Keep soldering irons away from plastic sleeves. For solder dipping, maintain temperature within 260 and duration not exceeding 10 seconds to prevent damage. |
| 15 | Hole Layout on Circuit Board | Ensure mounting hole spacing matches lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor. |
