Non-inductive Resistors Support High Frequencies

Members of Stackpole Electronics’ NWW series are non-inductive versions of the standard conformal coated, leaded, wirewound inductors of the WW series. The family supports power ratings from 0.6 W to 13 W. A non-inductively wound resistor has one winding in one direction and one in the other direction, a technique known as Ayrton-Perry winding.

Because of this, non-inductive wirewounds have an upper resistance range limit of one-half the value possible with a standard winding. For ease of use, Stackpole has listed a non-inductive resistance value range on their data sheets along with the standard range. Pricing ranges from $0.16 each to $1.06 each for minimum quantities.
