SOFT MAGNETIC THERMOSETTING FILM AND SOFT MAGNETIC FILM

摘要

The soft magnetic thermosetting film according to the present invention contains soft magnetic particles. The ratio (µ1'/µ0') of the initial relative permeability µ0' of the soft magnetic thermosetting film at a frequency of 1 MHz immediately after thermal curing thereof and the relative permeability µ1' at a frequency of 1 MHz when the soft magnetic thermosetting film has been left for 168 hours in an 85°C, 85% RH atmosphere is at least 0.85.
