Abstract

PURPOSE: To obtain the package which prevents vibration and can remove noises by a method wherein a ferrite bead is fast stuck previously to a mold formed in terminal arrangement equal to the terminal arrangement of a normal dual line package, and a pin conductor connected to a line which needs a noise preventive countermeasure is penetrated into the bead.
CONSTITUTION: The mold is formed in such a manner than a plurality of the pins 511W518, 521, 522, etc. are fitted on a package base 4a constituting the dual line package 4, and the surface is covered with a package cover 4b. In this constitution, the ferrite beads 31W34 are previously buried and fixed to the central section of the mold, and the pins 511W513 and 515 connected to a line which requires the noise preventive countermeasure are penetrated into the beads 31W34, and bent rectangularly at an end section of the base 4a. The pin 514 connected to a line which does not need the countermeasure is bent in a U-shaped form as a short circuit line, and the pins 516W518 connected in series with a capacitor, a resistor, etc. are bent in doglegged forms and each joined with the base 4a.
