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"
