A Dependence of loss factor tan(δ) upon H in MnZn ferrites

Tags:

    There is ηB constant given as a hysteresis material constant.
    But there is the question: what is the limit of applicability
    of the formula Δ(tan(δ)) = ηB⋅ΔB⋅μe?
    In particular I think I want to use ferrite with μi = 2000 or so.
    Up to what H value will tan(δ) increase linearly with B ?

    Can you post links to the ferrite datasheets that you've been reading to try to answer this question? Thanks.
