Unless your looking for a very high wattage, they "should" have what you need. Jeff |

Most anywhere that sells electronics parts. Most resistors are non
inductive. If you want inductive ones, you will have to look around a bit. "LHogan5782" wrote in message ... anyone know where i can find non inductive resistors thanks |

I have not seen carbon (comp) resistors at Radio Shack in many, many years.
Most of Shack's resistors are carbon film. The 1/4-watters are metal film. Shack also has 8 ohm non-inductive 20-watters. Those carbon film resistors are the kind to use for replacing high value resistors, especially those at the front end control grids, in old tube type radios, to get rid of the shot noise.

Caddock manufactures non inductive resistors.............they are in a
TO-220 package, and they are used in many dummy loads. There is one other company that manufactures tubular types with metallized ends, but I can't remember the name. It is something like Carbarundum. I have both types in my own stock, so I know that they do exist. Pete CW wrote in message ... Most anywhere that sells electronics parts.

The inductance of a fixed resistor depends quite a bit on the frequency
being used and the construction of the resistor. "Most resistors are non inductive" is a bit too general a statement, and can be incorrect in some cases. For instance, power resistors are often wirewound construction, which introduces significant inductance, even at HF frequencies. Many film resistors have significant inductance at VHF and UHF frequencies as well. Online distributors like Digi-Key and Mouser Electronics will offer some non-inductive types, but you need to be aware of the aforementioned variables when making your selection.

What is a function of frequency is the inductive reactance- which is directly porportional to frequency. Dale W4OP |
