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.
- SMT versions of the FTR-B4 relays will be shipped in "dry pack".
- MSL Moisture Sensitivity Level of the FTR-B4 relay is 2A.
