Models of equivalent physical and electrical specifications are available with non-inductive (Ayrton-Perry) winding. They are
identified by substituting the letter N for R in the model number (NS005, for example).
Two conditions apply:
1. For NS models, divide maximum resistance values by two
2. Body O.D. on NS02C may exceed that of the RS02C by 0.010"
