<P>PROBLEM TO BE SOLVED: To provide a power module that can prevent the generation of noises to the outside by enclosing all electrodes led from inner chips with a single noise absorber and embedding the noise absorber in a sealing gel for protecting the chip, and wherein its module main body is not necessary to be made larger because the noise absorber is installed alone. <P>SOLUTION: In the power module, a plurality of electrodes 8 to connect the chips with connection terminals are enclosed by a single ferrite core 15 at the same time, and the ferrite core chip is embedded in a gel silicon 14 for protecting chips. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
