Behaviour of dissipative resistor versus frequency

[SK245230]

Hi,

I have designed a DC to AC 1MHz converter and I would like to test it with different loads. I am expecting to use some dissipative resistors as in the link bellow.

I was wondering about the behaviour of this kind of resistor at different frequencies. Are they purely resistive around 1MHz or can it start to behave as inductor or capacitor. I have some doubts about this because it is said that those resistor are wirewounded which means that they should have some AC inductive behaviour.

Otherwise should I use such resistor to test my converter or is there a better way of doing it (current source...)?

The KAL series at the above link seems like not suited to work at higher frequencies.
Why don't you consider using the NKAL series instead ?

Arcol has published inductance specifications for their similar HS power resistor series. You'll see that resistor values below 100 ohm have usually an ESL/R zero below 1 MHZ.

I didn't yet see a specification for low-inductance series.

Ah yes I haven't seen that there were some non inductive rated resistors.
There are even some special RF resistors at 40$ https://www.digikey.com/product-search/en?keywords= TGHLV1K00JE-ND
But here again they don't give any characteristic or frequency range.

To Fvm: Thanks for the document.
