Precautions For Use
Multi-layer Ceramic Capacitors (MLCC) may fail in a short circuit or open circuit mode when subjected to severe conditions of electrical environment and/or mechanical stress beyond the specified rating and specified conditions. This may result in burn out, flaming or glowing in the worst case. Following precautions for safety and Application Notes shall be taken in your major consideration. If you have a question about the precautions for handling, please contact our engineering section or factory.
- Soldering Profile: To avoid crack problems due to sudden temperature change, follow the temperature profile in the adjacent graph.
- Manual Soldering: Manual soldering poses a risk of creating thermal cracks in capacitors. Ensure careful handling of the soldering iron, paying attention to tip selection and temperature contact.
