Usage Precautions
1. Aluminum electrolytic capacitors are polarized; ensure correct polarity. Reverse connection can cause short circuits or damage. Use non-polarized capacitors if polarity is uncertain or reversible.
2. Do not apply reverse voltage or DC voltage exceeding the rated voltage. Exceeding the rated voltage significantly increases leakage current and can cause damage. Using at rated voltage ensures optimal lifespan.
3. Ripple current should be less than the rated value. Exceeding the rated ripple current causes overheating, capacitance reduction, and shortened lifespan. The sum of the peak ripple voltage and DC voltage must be less than the rated operating voltage.
4. Operate within the rated temperature range. Operation above the upper limit significantly reduces lifespan or may activate the safety vent. Operation at room temperature ensures a longer lifespan. For every 10C decrease in ambient temperature, lifespan doubles.
5. Long-term storage can increase leakage current, especially at higher storage 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.
6. Not suitable for circuits with frequent charge/discharge cycles. Capacitance may decrease due to oxidation of the negative electrode film, or damage may occur from heat generated during charge/discharge.
7. Improper installation or stress on leads can damage the internal structure, leading to high leakage current or leakage issues. Ensure good soldering, proper PCB hole spacing, do not bend leads excessively, and avoid bending or twisting the capacitor body during soldering.
8. During tin dipping or soldering, the sleeve may crack or shrink due to excessive time or temperature.
9. Do not use halogenated organic solvents for cleaning. If cleaning is necessary, use a cleaner that guarantees capacitor quality. Do not store in cleaning solutions or sealed containers after cleaning. Dry with hot air (not exceeding the capacitor's upper temperature limit) for over 10 minutes along with the PCB.
10. Do not use halogenated organic compounds as fixing agents or coatings. Avoid sealing the capacitor's vent area with fixing or coating agents.
11. Recommended storage conditions: below 35, relative humidity less than 75% RH, away from direct sunlight. Product shelf life is 12 months from the manufacturing date. If stored beyond 12 months, check electrical characteristics and solderability.
12. For disposal, contact a local industrial waste disposal service.
13. Refer to EIAJ RCR-2367B for more details.
