* NOTES ON HANDLING 1.Recommended soldering conditions (Dip soldering) (1) Dip soldering
Temperature Time Cycle Flux 260 C or below (molten solder temperature) Less than 10 seconds. One cycle allowed to be dipped in solder including plastic mold portion.
Rosin flux containing small amount of chlorine (The flux with a maximum chlorine content of 0.2 Wt % is recommended.)
(2) Cautions
Fluxes Avoid removing the residual flux with freon-based and chlorine-based cleaning solvent.
2.Cautions regarding noise
Be aware that power is suddenly into the component any surge current may cause damage happen, even if the voltage is within the absolute maximum ratings.
