RECOMMENDED SOLDERING CONDITIONS
(TEMPERATURE PROFILE)
Note:
1.Temperature profiles show the tempera
ture of PC board surface.
2. Please perform soldering test with your
actual PC board before mass produc
tion, since the temperatures of PC
board surfaces vary according to the
size of PC board, status of parts mount
ing and heating method.

PRECAUTIONS
- For details on general precautions, refer to the section on technical descriptions.
- Since this is a polar relay, follow the instructions of the internal wiring diagram for the +- connections of the coil.
- Note that the terminal array and internal wiring of the surface mount relay are a top view.
