Sometimes Taiyo Yuden part numbers on label and packing slips may have their internal code (Prefix) listed, as per below. This supplier internal code is to specify certain Taiyo Yuden product groups in their product line only. The technical specification for these products are the same regardless of product code; this prefix has no effect at all on the part itself. Current Part Number Part The problem I am having is the markings, other than the voltage don't seem to corrolate with anything. So I'm not sure if it is a varistor or if it just has obscure markings. The markings are : 05 K385 1146 I know the k385 is the voltage from what I can find, but have no idea what the current is or what part number it matches up with.
