SOFT MAGNETIC THERMOSETTING FILM AND SOFT MAGNETIC FILM

摘要

A soft magnetic thermosetting film contains soft magnetic particles. The ratio (µ1'/µ0') of a relative magnetic permeability µ1' at a frequency of 1 MHz at the time of curing the soft magnetic thermosetting film by heating to be allowed to stand under an atmosphere of 85°C and 85%RH for 168 hours to an initial relative magnetic permeability µ0' at a frequency of 1 MHz immediately after curing the soft magnetic thermosetting film by heating is 0.85 or more.
