Precautions For Use
Multi-layer Ceramic Capacitors (MLCC) may fail in a short circuit or open circuit mode when subjected to severe electrical or mechanical stress beyond specified ratings and conditions. This can result in burn out, flaming, or glowing. Adhere to the following precautions and application notes:
- Soldering Profile: Follow the recommended temperature profile to avoid cracks due to sudden temperature changes.
- Manual Soldering: Exercise caution to prevent thermal cracks. Ensure the soldering iron tip is handled carefully, and pay attention to tip selection and temperature contact.
- Optimum Solder Amount for Reflow Soldering
- Recommended Soldering amounts
- Recommended Soldering Method: RReflow Soldering, WWave Soldering. Specific methods vary by size, temperature characteristic, rated voltage, and capacitance.
- Temperature Profile for Soldering: Keep the temperature difference between soldering temperature and surface temperature of chips 150 during preheating.
