Hi I am ganging 4 of these https://www.jameco.com/Jameco/Products/ProdDS/659956.pdf to create a 0.1 ohm current sense (20W) resistor. I have an actual precision current sense to compare it against. My concern is I am using a 7800Hz PWM load and these wirewound resistors may introduce some reactance that will throw off the sense results.
I was wondering if anyone has experience in using wirewound loads in a PWM train?
