Ersin is the tradename for a rosin type flux, just fine for electrical 
work.  Sn 50 means it's 50% tin (Sn), 50% lead (Pb), and it will work 
ok.  The melting point for 50/50 is a bit higher than for eutectic (sn 
63 or 67, I can't remember which).

Lead isn't a problem for electronics.  The RoHS stuff is concerned with 
the lead leaching out of the electronics later when it's crushed in a 
landfill.
