Additional Details

Aluminum electrolytic capacitors are polarized components and must be connected with the correct polarity to avoid damage. The operating temperature range is a critical parameter to consider, typically -40°C to +85°C or wider, though performance may be derated at higher temperatures. The ESR (Equivalent Series Resistance) is another important specification, influencing the capacitor's ability to handle ripple current. Consult the manufacturer's datasheet for complete specifications, including ESR, ripple current rating, leakage current, and operating temperature derating curves to ensure proper application and long-term reliability. The tolerance is typically ±20%.
