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...)?
