⚠️ Important Safety & Installation Notes
- Check the Voltage: Ensure your circuit’s peak operating voltage does not exceed 250V DC. Using this component in a 450V circuit will cause immediate component failure, smoking, or bursting.
- Observe Polarity: This is a polarized electrolytic capacitor. The long lead is the positive (+) terminal, and the short lead alongside the light-colored stripe is the negative (-) terminal. Reverse installation will destroy the capacitor.
- Discharge Before Handling: High-voltage capacitors can hold a dangerous electrical charge long after the power is turned off. Always safely discharge the capacitor before touching or soldering.
