• SDT30 = Product code and size

• -x2x = Turns ratio (first “x” = primary winding, “2” = “:” and second “x” = secondary winding)

• -yy = add “T7” for 7 inch tape-and-reel package. Leave blank for 5000 parts on 13 inch

• “-R” suffix = RoHS compliant

e.g., -127 = 1:7 primary to secondary turns ratio.
