Models of equivalent physical and electrical specifications are available with non-inductive (Aryton-Perry) winding. They are identified by substituting the letter N for R in the model number (NS-5, for example).
Two conditions apply: 1. For NS models, divide maximum resistance values by two 2. Body O.D. on NS-2C may exceed that of the RS-2C by 010"
