^ρPerminvar ferrites undergo irreversible changes to their electrical characteristics if subjected to strong magnetic ﬁelds or mechanical shock. The changes include an increase in permeability and loss factor. The increase in loss factor is especially pronounced at high frequency.
Data is derived from measurements on toroidal cores. These values cannot be directly transferred to products of another shape and size. The product related data can be taken from the relevant product speciﬁcations.
