ABSTRACT:
By appropriately determining the dimensions and positional relationships of the terminal pieces of an electronic component such as an electromagnetic delay line, the terminal pieces are capable of conducting super high speed signals without unduly attenuating or reflecting them. A signal terminal piece and a ground terminal piece situated in a common plane so as to define a gap G filled with dielectric material therebetween form an impedance line having a desired characteristic impedance. By selecting the gap from a range between 0.1 mm and 0.6 mm, it is possible to obtain a normally desired characteristic impedance when the dimensions of the terminal pieces and related parts are set to practical values. When a pair of ground terminal pieces are arranged on either side of a signal terminal piece, each of the gaps may be selected from a range between 0.1 mm and 1.0 mm when the gaps are air gaps, and from a range between 0.2 mm and 1.5 mm when the gaps are filled with dielectric material such as epoxy resin.
