Rated 1 A at 12 VDC, it mounts through-hole right-angle to the panel with an M6 threaded bushing and includes mounting hardware and a nut. Contact plating is nickel and tin; the housing is brass with a PBT insulator, and the part is ROHS3 compliant. ## Switch configuration across the SJ1 series The SJ1-3543 carries no internal switch, unlike the SJ1-3544 (single switch, 4 contacts) and the SJ1-3545N (two switches, 5 contacts) — all three share the same 3.50 mm mating diameter, 1 A rating, and panel-mount right-angle footprint. For a no-switch requirement the SJ1-3543 and the solder-termination SJ1-3533 are functionally identical; the SJ1-3543 uses kinked pins while the SJ1-3533 uses solder terminals.","metaTitle":"CUI Devices SJ1-3543 Phone Jack, 3.5mm Stereo, 1A, 12VDC","metaDescription":"CUI Devices SJ1-3543 phone jack, female, 3.50mm stereo TRS, panel mount right-angle, kinked pin termination, 1 A, 12 VDC, ROHS3 compliant, active production.","metaKeywords":null},"attributes":{"series":"SJ1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["USB, Type-C & HDMI Connectors","Audio Connectors"],"specifications":{"Mfr":"CUI Devices","Gender":"Female","Series":"SJ1","Package":"Bag","Features":"Mounting Hardware, Thread Lock","Includes":"2 pcs - 1 Connector, 1 Nut","Shielding":"Unshielded","Body Color":"Silver, Black","Termination":"Kinked Pin","Thread Size":"M6","Signal Lines":"Stereo (3 Conductor, TRS)","Body Material":"Brass","Cable Opening":"-","Mounting Type":"Panel Mount, Through Hole, Right Angle","Connector Type":"Phone Jack","Product Status":"Active","Actual Diameter":"0.142\\\" (3.60mm)","Panel Hole Size":"0.236\\\" (5.99mm)","Voltage - Rated":"12VDC","lifecycle_stage":"unknown","Contact Material":"Brass; Copper Alloy","Housing Material":"Polybutylene Terephthalate (PBT)","Insulation Color":"-","Internal Switch(s)":"Does Not Contain Switch","Base Product Number":"SJ1-35","Mating Length/Depth":"0.551\\\" (14.00mm)","Current Rating (Amps)":"1 A","Operating Temperature":"-25°C~85°C","Contact Material - Plating":"Nickel, Tin","Number of Positions/Contacts":"3 Conductors, 3 Contacts","Industry Recognized Mating Diameter":"3.50mm (0.141\\\", 1/8\\\", Mini Plug) - Headphone"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9800","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.98000","currency":"USD"},{"qty":10,"price":"$1.72300","currency":"USD"},{"qty":25,"price":"$1.65000","currency":"USD"},{"qty":50,"price":"$1.61320","currency":"USD"},{"qty":100,"price":"$1.53980","currency":"USD"},{"qty":250,"price":"$1.39320","currency":"USD"},{"qty":500,"price":"$1.28320","currency":"USD"},{"qty":1000,"price":"$1.09989","currency":"USD"},{"qty":2500,"price":"$1.02656","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/e94e043785fa0c54b8d086b5f983eddc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between the SJ1-3543 and the SJ1-3544?","answer":"The SJ1-3543 has no internal switch and 3 contacts; the SJ1-3544 has a single internal switch and 4 contacts.
