We have had trouble with some inductors from CoilCraft, although I believe they changed their process.  The problem was aqueous based flux technology ate through the insulation and exposed some of the turns to solder.  Switching suppliers of the inductors fixed this, but so did switching to another flux technology.

I have a colleague who is experiencing shorting issues with an SMD 0603 dual-wound Filter. Has anyone ever had issues with these components?
