Anyone using Sendust (Fe,Si,Al) to absorb stray EMI?


Sendust is a magnetic metal powder that was invented by Hakaru Masumoto at Tohoku Imperial University in Sendai, Japan, about 1936 as an alternative to permalloy in inductor applications for telephone networks. Sendust composition is typically 85% iron, 9% silicon and 6% aluminum.

Molex and Oyaide make tape and sheets with varying thickness to control stray EMI.

I have used the Oyaide Sendust sheets with power distribution builds. I find it works best with power distribution. 
I would enjoy hearing others experiences.

Hi geoffkait,

clearly you are qualified to make these points?!?! Your website of tweaks  (machina dynamica) - omg...

Sendust does have more than one application
I believe they are referring to EMI (further up the spectrum sir) - and yes this material does absorb it. This is actual science not hearsay. If you bother to do your research you would know that.

But please enlighten us with your bag or tricks?!?!
Wow, you guys are hilarious,

Please enlighten the world and delete posts that speak to the truth.

Sorry guys, I have to get back to actually working on the Albums you purchase.
