Product details

2.5 mm stereo jack, 1 A at 12 VDC

The SJ-2504N is the 3-conductor, 4-contact member of CUI Devices' SJ phone jack series, mating with a standard 2.50 mm (3/32") stereo plug. Rated 1 A at 12 VDC, the tin-plated brass contacts and single internal switch suit signal-level audio switching in panel-mount or board-edge applications.

Through-hole right-angle vs SMT siblings

Within the SJ-25 base series, the SJ-2504N uses a through-hole right-angle termination, while the SJ-2524-SMT-TR and SJ-2523-SMT-TR use surface-mount right-angle — the board footprint differs, but the 2.50 mm mating diameter, 1 A rating, and unshielded construction are shared across the three.
