Usage Precautions
1. Polarity: Aluminum electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use non-polarized capacitors for circuits with uncertain polarity.
2. Voltage: Do not apply reverse voltage or DC voltage exceeding the rated voltage. Operating at rated voltage ensures longevity. Surge voltage is the maximum voltage the capacitor can withstand for a short duration.
3. Ripple Current: Keep ripple current below the rated value. Exceeding the rated value can cause overheating, capacity reduction, and shortened lifespan. The sum of peak ripple voltage and DC voltage should not exceed the rated working voltage.
4. Temperature: Operate within the rated temperature range (-40 to +105). Operating above the upper limit significantly reduces lifespan or may activate the safety vent. Lowering ambient temperature by 10 can double the lifespan.
5. Storage: Long-term storage can increase leakage current, especially at higher temperatures. Store in a cool, dry environment. Leakage current will decrease after applying voltage. Pre-charge if high leakage current affects the circuit.
6. Frequent Charge/Discharge: Not suitable for circuits with frequent charge/discharge cycles, as it can lead to capacity reduction or damage due to heat generation.
7. Installation Stress: Avoid poor installation or stress on leads, which can damage internal structure, leading to high leakage current or leakage. Ensure good soldering, proper PCB hole spacing, do not bend leads excessively, and do not bend or twist the capacitor body when soldering.
8. Soldering/Dipping: Prolonged or excessive heat during tinning or soldering may cause the sleeve to crack or shrink.
9. Cleaning: Do not use halogenated organic solvents for cleaning. If cleaning is necessary, use approved solvents. After cleaning, dry with hot air (not exceeding the upper temperature limit) for over 10 minutes.
10. Fixatives/Coatings: Do not use halogenated organic fixatives or coatings. Avoid sealing the capacitor's safety vent area.
11. Storage Recommendation: Store in an environment below 35, with relative humidity less than 75% RH, and out of direct sunlight. Shelf life is 12 months. Check electrical characteristics and solderability if stored beyond this period.
12. Disposal: Contact local industrial waste disposal services for end-of-life products.
13. Further Information: Refer to EIAJ RCR-2367B.
