The GMPI series is magnetically shielded chip based on multilayer process.
New magnetic material is developed to get excellent direct current characteristics.
This series has larger rated current than conventional GMLI series.
Low DC resistance is realized.
The cross talk characteristics are excellent because of the magnetically shielded
structure.
