Is this resistor non-inductive…?

Hello,

Thank you for your inquiry.

According to the manufacturer’s documentation that part is not listed as non-inductive.

Thanks for that help. I’m not sure which resistors on the site are non inductive. Could you recommend a product no. Of a 450 Ohm non inductive resistor. This part is going to be used to build an amateur radio antenna.

All resistors will become inductive at some frequency; the “non-inductive” ones are simply designed with an eye toward limiting the effect. Simply wrapping a bunch of turns of wire around a core/former can (for example) give a device marketable as either a “resistor” or “inductor”, depending on the properties of the wire and core…

That aside, such “non-inductive” resistors are delineated on the site by annotation in the “features” column. I’d suggest navigating to the resistor family of choice ([through-hole](https://www.digikey.com/en/products/filter/through-hole-resistors/53), I suspect) and using the “search within” function to filter for such.

The non-inductive resistors will indicate this under Features.

We don’t have anything in 450 Ohms. 430 and 470 Ohms is the closest standard values we have.
