It integrates the magnetics and decoupling capacitance directly into the connector body — no external transformer or common-mode choke needed on the PCB. The shielded shell with EMI finger provides a low-impedance path to chassis ground, reducing radiated emissions at the I/O port. Dual green LEDs indicate link and activity status. The 0.555\" (14.10mm) height above board is a standard profile for panel-mount RJ45 jacks in 1U equipment. ## Key Specifications for 10/100 Base-T Rated for 10/100 Base-T operation with AutoMDIX, the jack handles automatic crossover detection and correction — no need for crossover cables or manual MDI/MDIX switching. The integrated magnetics include the transformer and common-mode choke for the 6 cores per jack, covering the full signal path for 10/100 Mbps. Operating temperature range is 0°C to 70°C, suitable for indoor commercial and industrial equipment. The housing is PET/polyester with UL94 V-0 flame rating (implied by the material class). ## Mechanical Fit and Board Layout The 90° right-angle orientation places the RJ45 port parallel to the PCB, allowing the connector to sit flush with the panel edge. The 0.555\" (14.10mm) height above board is a standard dimension for 1U rack-mount equipment; verify the enclosure cutout and panel thickness to ensure the tab direction (up) aligns with the cable exit. The through-hole solder termination requires plated through-holes in the PCB footprint — no SMT reflow profile needed.","metaTitle":"6-6605786-1 Mag45 RJ45 Jack, 10/100 Base-T, Obsolete","metaDescription":"6-6605786-1 Mag45 RJ45 jack, 1-port, 90° right-angle, through-hole, shielded with EMI finger, green LEDs, 0.555\" board height.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Modular / RJ Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"Mag45","Package":"Tray","Features":"Board Lock, Decoupling Capacitance","LED Color":"Green - Green","Shielding":"Shielded, EMI Finger","Orientation":"90° Angle (Right)","Termination":"Solder","Applications":"10/100 Base-T, AutoMDIX","Mounting Type":"Through Hole","Tab Direction":"Up","Connector Type":"RJ45","Contact Finish":"Gold","Number of Rows":"1","Product Status":"Active","Number of Ports":"1","Shield Material":"Brass","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Housing Material":"Polyethylene Terephthalate (PET), Polyester","Height Above Board":"0.555\\\" (14.10mm)","Base Product Number":"6605786","Operating Temperature":"0°C ~ 70°C","Contact Finish Thickness":"50.0µin (1.27µm)","Number of Cores per Jack":"6"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.6700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9f75cdb25d81ec0a052d4243ee167e5e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 6-6605786-1 obsolete and still available?","answer":"Yes, the 6-6605786-1 is officially obsolete.
