Chemi-Con Capacitor Selection Guide
Chemi-Con Capacitor Selection Guide
Selecting the right aluminum electrolytic capacitor requires understanding your application requirements and matching them to the appropriate Chemi-Con series.
Understanding Capacitor Specifications
Capacitance: The amount of charge a capacitor can store, measured in microfarads (uF). Select based on energy storage or filtering requirements.
Voltage Rating: The maximum DC voltage the capacitor can withstand. Always apply 20-50% derating for reliable operation.
Ripple Current: The maximum AC current the capacitor can handle without excessive heating. Higher ripple current capability means better performance in switching applications.
Temperature Rating: The maximum operating temperature. 105°C is standard for industrial, 125°C or 150°C for automotive.
Lifetime: Rated operating hours at maximum temperature. Actual lifetime extends significantly with lower operating temperatures.
