Sendust appears to be a type of mu metal, aka Kool Mu, high permeability alloy used to absorb magnetic fields in transformer applications, for example, not RF, which is a horse of a different color. 🦓 Examples of materials that are good for RF absorption/shielding include high-conductivity graphene, carbon fiber cloth, copper sheeting.
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.
