ては無視し得ないものとなる。 However, since this jab dipping is performed manually, there will be large variations in the dimensions between the root portion 9a and the preliminary solder attachment surfaces of the three sets of terminals. Since the positions of the ends 10b and 11b to be soldered to the copper foil part 3 are determined by the position of this preliminary soldering surface, the coil winding 10 from the root part 9a of the core 9 to the copper foil part 3 ends up being ,11
There was considerable variation in the length, ie, the value of dimension L in FIG. Such variations increase or decrease the inductive reactance or capacitive reactance of the lead wire from the high-frequency transformer to the printed circuit board connection, so it can be ignored for mass-produced electronic circuits that require certain electrical characteristics. It becomes impossible.
