Are your typical Radio Shack metal oxide resistors non-inductive?

Thanks,

Even just a straight length of wire has *some* inductance. MOVs are
characteristically capacitive, though.

They are usually spiral cut, so have a little inductance.

Low value resistors, under maybe 100 ohms, behave a little
inductively, but are fine up into the hundreds of MHz. Big values,
Kohms, are mostly capacitive.

Here's a cheap 51 ohm resistor

and here's its TDR step response

Note that it's pretty much settled down in a few hundred picoseconds.
The little ringy thing is at 9.6 GHz.

** Resistors are described as "' non-inductive" if their design prevents any
excess inductance being created.

Examples are carbon composition and bi-filar wound wire resistors.

All capacitors are " non -inductive " by design - ie the wound foil strips
are connected all along the edges.

However, at radio frequencies a given resistor may ACT inductively or
capacitively depending of its physical size, electrical value and the actual
frequency.

Inductance and capacitance are ultimately inescapable.

the capacitor statement is not true.

Or what?

what are you going to do? Type in caps? Cuss a little? Slap your keyboard
around like I do your mother?

Please, enlighten me.

** That is not the SR frequency of that cap.

The cap's ESR is not 5.7 ohms either.

And none of this has any relevance to my post.


The part that's relevant to your post was the fact that you said that

All capacitors are " non -inductive " by design - ie the wound foil
strips are connected all along the edges.

which clearly isn't so.

** The first part is absolutely true.

The words after " - ie" are simply not needed.

But the OP would never have got the basic idea if I omitted them.

All you came along and did was shift the context and make an absolute,
fucking ass of yourself again.

And destroy the above NGs a bit more.

Asshole.

If you build a robotic machine that builds other robotic machines that
assemble ATM machines, would that be an automatic automatic automatic

Only if the machines produced other machines that did their work without being
told to, else s/automatic/automated/. ...and you've blown the stack unrolling
the recursion (unless you're one who says you're "going down to the ATM
machine").

If that were the case, the firmware would crash very soon! you have
three automatic entries with four Returns = Stack corruption!

Yeah, the "ATM machine" was supposed to be the point of the whole thing;
sorry if I didn't make clear right away.

And they abandoned the anti-anti-missile missile missile project decades
ago. )-;
