WARD LEONARD - RWF60W200 - BR200WL - NI Resistor, Ceramic.

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.

Applications: A non inductive resistance is a resistance which has no inductance. Such, resistance are required in high frequencies as well as in high speed digital circuit. The magnetic field generated by each other cancel out each other effect.
