Note: This is a polarized capacitor and must be connected with the correct polarity. Reversing the polarity or applying a voltage higher than 25V DC may damage the capacitor or cause it to fail. Ensure the capacitor’s voltage rating is higher than the maximum operating voltage in your circuit for reliable operation.
