Usage Precautions
- Polarity: Aluminum electrolytic capacitors are polarized. Ensure correct connection to avoid short circuits or damage. Use non-polarized capacitors if polarity is uncertain or may be reversed.
- Voltage: Do not apply reverse voltage or DC voltage exceeding the rated voltage. Exceeding rated voltage significantly increases leakage current and can cause damage. Use at rated voltage for optimal lifespan. Surge voltage is the maximum voltage the capacitor can withstand for short durations.
- Ripple Current: Ripple current should be less than the rated value. Exceeding the rated ripple current can cause overheating, capacitance reduction, and shortened lifespan. The peak value of applied ripple voltage plus the DC voltage should be less than the rated working voltage.
- Temperature Range: Use within the rated temperature range. Operating above the upper limit will significantly shorten lifespan or activate the safety vent. Operating at room temperature ensures a longer lifespan. For every 10C decrease in ambient temperature, lifespan doubles.
- Long-term Storage: Leakage current may increase after long-term storage, especially at higher temperatures. Store in a suitable environment. Leakage current will decrease after applying voltage. If increased leakage current affects the circuit, pre-charge the capacitor before use.
- Frequent Charge/Discharge: Not suitable for circuits with frequent charge/discharge cycles. Capacitance may decrease due to oxidation of the negative electrode's oxide film, or damage may occur from heat generated during charge/discharge.
- Installation: Improper installation or stress on leads can damage the internal structure, leading to high leakage current or leakage issues. Ensure good soldering, correct PCB hole spacing, do not bend leads excessively, and avoid bending or twisting the capacitor body during soldering.
- Soldering: Prolonged or excessively high-temperature soldering may cause the sleeve to crack or shrink. Use appropriate soldering times and temperatures.
- Cleaning: Do not use halogenated organic solvents for cleaning. If cleaning is necessary, use a cleaner that guarantees capacitor quality. After cleaning, do not store in the cleaning solution or sealed containers. Dry the capacitor and PCB with hot air for over 10 minutes, ensuring the hot air temperature does not exceed the capacitor's upper temperature limit.
- Fixing Agents/Coatings: Do not use halogenated organic series fixing agents and coating agents. Do not seal the capacitor's sealing area completely with fixing or coating agents.
- Storage Recommendation: Store in an environment of ~35, relative humidity less than 75% RH, away from direct sunlight. The product's shelf life is 12 months from the date of manufacture. If stored beyond 12 months, check electrical characteristics and solderability.
- Disposal: When disposing of capacitors, contact a local industrial waste disposal service.
- Further Details: Refer to EIAJ RCR-2367B for more information.
