Note: This is a polarized capacitor and must be connected with the correct polarity. Reversing the polarity or applying a voltage greater than 25V DC may damage the capacitor or cause failure. For maximum reliability, use the capacitor within its rated voltage and temperature limits, and keep it away from high-temperature components.
