KNSCHA 189RV166

Non-solid chip aluminum electrolytic capacitor, AG series, 4.7μF, 400V, Φ8×12.5mm, 105°C, ±20%, SMD

• Aluminum electrolytic capacitors self-heat under ripple current, causing temperature rise and aging — every 5°C increase in temperature halves the service life
• Recommended maximum reflow cycles: 2
• If a second reflow is required, ensure the capacitor has fully cooled to room temperature (5 - 35°C) after the first reflow
• Maximum temperature rise rate: 5°C per second (average)
• Maximum temperature fall rate: 6°C per second (average)
• Maximum time from 25°C to peak temperature: 6 minutes
• Aluminum electrolytic capacitors are polarized — must be installed with correct polarity
• Do not apply reverse voltage or DC voltage exceeding the rated voltage
• Ripple current must remain below the rated value; the sum of the peak ripple voltage and DC voltage must not exceed the rated working voltage
• Use capacitors within the rated temperature range
• Leakage current increases after prolonged storage; it will gradually decrease once voltage is applied
• Not suitable for circuits with frequent charge/discharge cycles
• Improper installation or mechanical stress on leads may damage the internal structure
• During tinning or soldering, the sleeve may crack or undergo secondary shrinkage if soldering time is excessive or temperature is too high
• Do not clean aluminum electrolytic capacitors with halogenated organic solvent-based cleaners
• Do not use fixing agents or coating agents containing halogenated organic compounds
• Recommended storage conditions: 5~35°C, relative humidity below 75%RH, away from direct sunlight; shelf life from date of manufacture is 12 months
