Alternative to Mundorf M-Resist bifilar resistor

[Audiophile100%]

Hi,
i'm searching an alternative to Mundorf M-Resist resistor.
that's bifilar resistor technology
could you suggest me same supplier ?

does expotus uses this type of construction ?

thank you

Unfortunately there's no way to tell from the information in the links if they use bifilar non-inductive wound configurations.


There aren't many good alternatives to the Mundorf M-Resist series; I use them pretty much exclusively, and a number of high end manufacturers (Magico, for example) use them too. Mills resistors are non-inductive wound, but only rated for 12W, not 20W.

thank you jon.

are these superior to m-restist ?

they have no inductance and no capacitance,
the bifilar tech has capacitance element

That looks like it's a Mills resistor. Mills is now part of Vishay. If you click on the MRA Datasheet link it comes up Vishay Mills.

Vishay has some other film type resistors that are very low inductance, which I've used in amplifier applications. the thing for any resistor if you want to know what it does is look at it in detail on a network impedance analyzer like an HP 4192, which I use, and look at the ESL as well as determine the effective self resonance frequency due to parallel capacitance. At the impedances of speaker network resistors, the parallel C results in a self resonant frequency far, far above the operating range- ESL is usually more of a factor. But even then, it's often over emphasized considering what happens in the bandwidth up to 100 kHz. Just like wire coils versus foil coils- usually the best argument for foil coils is packing space and achievable DCR, not any inductance variation due to skin effect.

hi jon,
how are you ?

did you compared mundorf m-resist supreme vs jantzen mox ?
