Notes

1. The above temperature shall be measured 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 material, size thickness of PC boards

and others. 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.
