Key features

• Non-solid SMD aluminum electrolytic capacitor, spec: AS, 100uF, 16V, Φ6.3×4.5mm, 105°C ±20%
• Aluminum electrolytic capacitors age due to self-heating from ripple current superposition and temperature rise; every 5°C increase in temperature halves the service life
• Recommended reflow count: no more than 2 times
• For a 2nd reflow, ensure the capacitor has cooled to room temperature (5–35°C) after the 1st reflow
• Maximum temperature rise: 5°C per second (average)
• Maximum temperature drop: 6°C per second (average)
• Maximum time from 25°C to peak temperature: 6 minutes
• Aluminum electrolytic capacitors are polarized; must be used with correct polarity
• Do not apply reverse voltage or DC voltage exceeding the rated voltage; recommended to operate at rated voltage
• Ripple current must be below the rated value; the sum of the peak ripple voltage and DC voltage must not exceed the rated working voltage
• Operate within the rated temperature range; use at room temperature ensures longer service life — every 10°C decrease in ambient temperature doubles the service life
• Leakage current may increase after prolonged storage; it will decrease gradually after voltage is applied. If elevated leakage current adversely affects the circuit, pre-charge the capacitor before use
• Not suitable for circuits with frequent charge/discharge cycles
• Improper mounting or mechanical stress on leads may damage the internal structure, causing high leakage current or electrolyte leakage
• The sleeve may crack or undergo secondary shrinkage if soldering time is too long or temperature is too high
• Do not clean aluminum electrolytic capacitors with halogenated organic solvent-based cleaners; if cleaning is necessary, use a verified-quality cleaner, then dry with hot air for at least 10 minutes at a temperature not exceeding the capacitor's upper temperature limit
• Do not use fixatives or coating agents containing halogenated organic compounds; do not allow them to seal the vent area of the capacitor
• Recommended storage conditions: 5–35°C, relative humidity below 75%RH, away from direct sunlight; shelf life from date of manufacture is 12 months; electrical characteristics and solderability must be inspected after 12 months
