Usage Precautions

• Aluminum electrolytic capacitors are polarized; ensure correct polarity during use. Reverse connection can cause short circuits or damage. Use non-polarized capacitors if polarity is uncertain or may be reversed.
• Do not apply reverse voltage or DC voltage exceeding the rated voltage. Exceeding the rated voltage significantly increases leakage current and can lead to capacitor damage. Use at rated voltage for optimal lifespan. Surge voltage is the maximum voltage the capacitor can withstand for a short duration.
• Ripple current should be kept below the rated value. Exceeding the rated ripple current can cause internal heating, capacitance reduction, and shortened lifespan. The sum of the peak ripple voltage and the DC voltage should not exceed the rated working voltage.
• Operate capacitors within the rated temperature range. Operation above the upper limit temperature will drastically reduce lifespan or activate the safety vent. Operation at room temperature ensures a longer lifespan. Scientific statistics show that for every 10 decrease in ambient temperature, the lifespan doubles.
• After prolonged storage, leakage current may increase, especially at higher storage temperatures. Store in a suitable environment. Leakage current will decrease after voltage is applied. If increased leakage current affects the circuit, pre-charge the capacitor before use.
• Capacitors are not suitable for circuits with frequent charge and 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.
• Improper installation or stress on leads can damage the internal structure, leading to high leakage current or leakage issues. Ensure good soldering, appropriate PCB hole spacing, do not bend leads excessively, and avoid bending or distorting the capacitor body during soldering.
• During tin dipping or soldering, the sleeve may crack or shrink due to excessive time or temperature.
• Do not use halogenated organic cleaning agents. If cleaning is necessary, use agents that guarantee capacitor quality. After cleaning, do not store in the cleaning solution or sealed containers. Dry the capacitor and PCB with hot air for at least 10 minutes, with the hot air temperature not exceeding the capacitor's upper temperature limit.
• Do not use fixatives or coatings containing halogenated organic compounds. Avoid completely sealing the capacitor's sealing area with fixatives or coatings.
• Recommended storage conditions: below 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.
• For disposal of used capacitors, contact a local industrial waste disposal service.
• Refer to EIAJ RCR-2367B for more details.
