RESISTOR TYPE FOR INDUCTIVE CIRCUIT

[gismo]

I HAVE HEARD THAT A WIRE WOUND RESISTOR IS BEST <br>FOR AN INDUCTIVE CIRCUIT.CARBON AND METAL FILM ARE NOT <br>PREFERRABLE. IS THIS TRUE AND WHY?

 

[azzmi]

Hi,<br>I don't think it is true. In my opinion opposite of this comment can be true. I mean the wirewound resistor is the worst for a non inductive circuit because of its big parasitic inductance.(if you don't want to add some serial parasitic inductance to your circuit.)<br>I think the main advantage of wirewound resistors is, they can handle (or dissipate) more power than the others with less volume.&nbsp;&nbsp; <p>Azmi Demirel<br><a href=mailto:azzmi@elk.itu.edu.tr>azzmi@elk.itu.edu.tr</a><br><a href=

Azmi is essentially correct. However, there are so-called &quot;non-inductive&quot; wirewound resistors in which the resistive wire element is given a bifilar construction. That tends to reduce the inductance the resistor would otherwise have, although not eliminate it altogether.<br><br>John Dunn<br>Ambertec, Inc.

Hi,<br>John, would you compare non-inductive wirewound resistors with the other types (metal or carbon film resistors and even water resistors). Is the bifilar construction the best (by mean of parasitic inductance)? <p>Azmi Demirel<br><a href=mailto:azzmi@elk.itu.edu.tr>azzmi@elk.itu.edu.tr</a><br><a href=
