Process for making molybdenum-permalloy metal dust cores

摘要

In the case of a process for making molybdenum-permalloy metal (MPM) powder cores which have an initial permeability of 100 to 250 and a Q of more than 50 in the frequency range from 20 to 100 kHz, a molybdenum-permalloy metal powder is used having a grain size of at most 63 mu m and a grain median of less than 10 mu m.
