The STX-35398 series middle-mount stereo jacks enable more flexibility for board-mount designs in applications that are continuously requiring smaller and lower profiles plus higher functions such as portable audio equipment and mobile phones. The components comply with EIA standards and are available with a 3.5-mm diameter opening, three-pole with one open switch, and five pins. The series includes two styles: STX-35398A-5N-TR mid-mount with through-hole and surface-mount contacts with barrel and the STX-35398E-5N-TR mid-mount with through-hole contacts without barrel.
