Guidelines For Using Aluminum Electrolytic Capacitor
To ensure optimal capacitor performance and longevity, please observe the following guidelines:
- Polarity: DC electrolytic capacitors are polarized. Ensure correct polarity is observed as marked on the capacitor body. Reversed polarity can cause short circuits or damage. Use bipolar capacitors if polarity is uncertain. DC electrolytic capacitors are not suitable for AC applications.
- Operating Voltage: Do not apply voltage greater than the rated voltage. Exceeding the rated voltage increases leakage current and may damage the capacitor. Recommended working voltage is 70-80% of the rated voltage to prolong life.
- Ripple Current: Do not allow excessive ripple current through the capacitor. Exceeding the permissible ripple current can cause heating, reduced capacitance, and damage. Ensure ripple current does not exceed the allowable value.
