Notes  
1. The condition mentioned above is the temperature on the mounting surface of a PC board. There are cases where  
the PC board's temperature greatly differs from that of the switch, depending on the PC board's material, size,  
thickness, etc. The above-stated conditions shall also apply to switch surface temperatures.  
2. Soldering conditions differ depending on reflow soldering machines. Prior verification of soldering condition is  
highly recommended.
