Rated 1 A at 12 VDC, it mounts through-hole right-angle with kinked pins and includes two internal switches for contact detection. ## Contact arrangement and switching The 3-conductor TRS configuration routes left, right, and ground signals across 5 contacts; the two internal switches detect plug insertion or tip-ring bridging. Nickel and tin plating on the brass and copper alloy contacts provides sufficient cycle life for consumer and light-industrial audio jacks.","metaTitle":"CUI Devices SJ1-3545N 3.5mm Stereo Phone Jack, 3 Conductor","metaDescription":"CUI Devices SJ1-3545N phone jack: 3.50mm industry mating diameter, stereo TRS, through-hole right-angle, 1 A, 12 VDC, unshielded, 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":"-","Includes":"-","Shielding":"Unshielded","Body Color":"Black","Termination":"Kinked Pin","Thread Size":"-","Signal Lines":"Stereo (3 Conductor, TRS)","Body Material":"Brass","Cable Opening":"-","Mounting Type":"Through Hole, Right Angle","Connector Type":"Phone Jack","Product Status":"Active","Actual Diameter":"0.142\\\" (3.60mm)","Panel Hole Size":"-","Voltage - Rated":"12VDC","lifecycle_stage":"unknown","Contact Material":"Brass; Copper Alloy","Housing Material":"Polybutylene Terephthalate (PBT)","Insulation Color":"-","Internal Switch(s)":"Two Switches","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, 5 Contacts","Industry Recognized Mating Diameter":"3.50mm (0.141\\\", 1/8\\\", Mini Plug) - Headphone"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4600","priceTiers":[{"qty":1,"price":"$1.46000","currency":"USD"},{"qty":10,"price":"$1.27200","currency":"USD"},{"qty":25,"price":"$1.21800","currency":"USD"},{"qty":50,"price":"$1.19100","currency":"USD"},{"qty":100,"price":"$1.13690","currency":"USD"},{"qty":250,"price":"$1.02860","currency":"USD"},{"qty":500,"price":"$0.94738","currency":"USD"},{"qty":1000,"price":"$0.81204","currency":"USD"},{"qty":2500,"price":"$0.75790","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/1d81e213dfb19e659d493d64adecd25b.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/SJ1-3545N/alternatives.json"},"ai":{"faq":[{"question":"What is the industry mating diameter for the SJ1-3545N?","answer":"The jack accepts a 3.50 mm (0.141\", 1/8\") mini plug — the standard headphone/audio connector diameter.
