3.50 mm stereo jack, 3-conductor TRS
The SJ2-35853A-SMT-TR is the 3-conductor (TRS) member of CUI Devices' SJ2 phone jack family, accepting a standard 3.50 mm mini plug. Rated 1 A at 12 VDC with silver-plated contacts, it handles line-level audio signals without internal switching.
Position count vs. sibling SJ2 jacks
Within the SJ2 series the 3-conductor SJ2-35853A-SMT-TR sits alongside 4-conductor (TRRS) siblings such as the SJ2-3574A-SMT-TR and the SJ2-35954A-SMT-TR — the 3.50 mm mating diameter, 1 A rating, and SMT right-angle footprint are shared across the series, so the conductor count is the selection axis. A further sibling, the SJ2-35894B-SMT-TR, adds a single internal switch for detect circuits while keeping the same 4-conductor signal path.
