Dear all,

 

I have a received a box with about a dozen toroids= in different sizes (0.5 to 2 inch diameter), they all are be made of= MOLYPERMALLOY (MPP) material (brands Arnold and Magnetics).

From what I found on the web this material se= ems to be used as a better alternative to ferrite (higher flux density, be= tter temperature stability).

Does anyone have experience woth this material on= 136/500kHz ?
