| Precautions For Use | |||
| Soldering Profile | To avoid the crack problem by sudden temperature change, follow the temperature profile in the adjacent graph. | ||
| Manual Soldering | Manual soldering can pose a great risk of creating thermal cracks in capacitors. The hot soldering iron tip comes into direct contact with the end terminations, and operators careless may cause the tip of the soldering iron to come into direct contact with the ceramic body of the capacitor. Therefore the soldering iron must be handled carefully, and pay much attention to the selection of the soldering iron tip and temperature contact of the tip. | ||
| Optimum Solder Amount for Reflow Soldering | |||
| Recommended Soldering Method | |||
| Temperature Profile for Soldering | While in preheating, please keep the temperature difference between soldering temperature and surface temperature of chips as: T150. | ||
