WARD LEONARD - RWF225W5 NI - Resistor, ceramic, Non Inductive.

A non-inductively wound resistor uses Ayrton-Perry Winding technique which has one winding in one direction and one in the other. Since there are the same number of turns of wire in each direction, the magnetic fields of the two wires cancel each other to nullify inductance. One disadvantage of this technique is that it requires twice the length of coil to make given resistance as compared to standard winding. Ayrton-Perry windings are used in resistor to eliminate parasitic inductance at high frequencies.

Vishay DALE - NHL25-10R - Resistor, Ceramic.

Ayrton–Perry windings of resistance wire used to make wirewound RF resistors are used at high frequencies, where inductance and capacitance are unwanted.

The winding is made of two separate wires wound in opposing directions along an insulating form and connected in parallel at the ends. Since there are the same number of turns of wire in either direction, the magnetic fields of the two wires cancel each other out, so the coil has little inductance; and since adjacent turns of the two wires are at approximately the same voltage, there is little parasitic capacitance between the turns.

One disadvantage is that because the two lengths of resistive wire are connected in parallel, four times the length of wire (twice the length for each coil) is needed to make a given resistance, compared to when a single coil is used so they are more expensive than inductive wirewound resistors.
