    • A surface mount connector has a dielectric housing with first and second opposing mating faces. The first mating face includes first terminals and the second mating face includes second terminals. The first and second terminals each have a tail portion, a contact portion and a terminal retention portion. The terminal retention portion engages the connector housing, and an opening, or hole, is formed in the retention section of the terminal. This opening is sized to keep sufficient metal remaining to retain the terminal in the housing, yet having sufficient surface area to provide a desired capacitance and/or inductance for tuning the impedance of the terminal to the preselected level, the second terminals each having a second terminal retention section with a central portion removed thereof, the removed central portion being spaced away from the first terminal retention area, while minimizing the surface area, size and shape of the central section for tuning the impedance of the terminal to a preselected range.
    • 表面安装连接器具有电介质外壳,其具有第一和第二相对配合面。 第一配合面包括第一端子,第二配合面包括第二端子。 第一和第二端子各自具有尾部,接触部分和端子保持部分。 端子保持部分接合连接器壳体,并且在端子的保持部分中形成开口或孔。 该开口的大小适于保持足够的金属以将端子保持在壳体中,但是具有足够的表面积以提供用于将端子的阻抗调谐到预定电平的期望的电容和/或电感,每个第二端子具有第二 端子保持部分,其中心部分被去除,所移除的中心部分与第一端子保持区域间隔开,同时最小化用于将端子的阻抗调谐到预选范围的中心部分的表面积,尺寸和形状。
