The power coil type MCOIL™ series: MA and MD series are characterized by a metal magnetic core with permeability that is nearly two times that of traditional composite types. A high-permeability resin allows for good shielding. The wound wire core in the MA and MD series allows for high wounding accuracy and the bottom electrodes pose no risk of short circuiting when component touches the shield case. These series have a low DCR and small case sizes compared to traditional ferrite inductors.
