Note: 1.Temperature profiles show the temperature of PC board surface.
2.Please perform soldering test with your actual PC board before mass production, since the temperatures of
PC board surfaces vary according to the size of PC board, status of parts mounting and heating method.
n PRECAUTIONS
- For details on general precautions, refer to the section on technical descriptions.
- Since this is a polarized relay, follow the instructions of the internal wiring diagram for the ± connections of the coil.
- Note that the terminal layout and internal wiring of the surface mount relay are a top view
