Panel stops set a consistent depth when the jack is mounted through a cutout in the enclosure or panel — no need for a separate spacer or alignment fixture. This combination simplifies the build sequence for panel-mount Ethernet ports. ## Unshielded Design: When to Use It This jack is unshielded, so it relies on the system's overall EMI strategy rather than providing a local shield can for cable-side grounding. It is a good fit for applications where the cable run is inside a grounded metal enclosure, or where the Ethernet PHY and routing are already isolated from noise sources. For runs through high-EMI environments or where the cable exits the enclosure, a shielded jack with a drain wire termination would be the alternative.","metaTitle":"TE Connectivity 5520259-4 Modular Jack, 8P8C RJ45","metaDescription":"TE Connectivity 5520259-4 modular jack, 8P8C (RJ45) vertical unshielded, through-hole with board lock and panel stops. 50µ\" gold contacts, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Modular / RJ Connectors","Modular Jacks (RJ)"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"-","Package":"Tray","Ratings":"Cat3","Features":"Board Lock, Panel Stops","LED Color":"Does Not Contain LED","Shielding":"Unshielded","Orientation":"Vertical","Termination":"Solder","Mounting Type":"Through Hole","Tab Direction":"User Selectable","Connector Type":"Jack","Contact Finish":"Gold","Number of Rows":"1","Product Status":"Active","Number of Ports":"1","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Housing Material":"Polybutylene Terephthalate (PBT), Polyester","Ingress Protection":"-","Base Product Number":"5520259","Operating Temperature":"-40°C ~ 85°C","Contact Finish Thickness":"50.0µin (1.27µm)","Number of Positions/Contacts":"8p8c (RJ45, Ethernet)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6600","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.66000","currency":"USD"},{"qty":10,"price":"$1.51600","currency":"USD"},{"qty":25,"price":"$1.47120","currency":"USD"},{"qty":114,"price":"$1.35158","currency":"USD"},{"qty":342,"price":"$1.32918","currency":"USD"},{"qty":1026,"price":"$1.08277","currency":"USD"},{"qty":2508,"price":"$1.00062","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/345fd023b5f0513d753c725f5b068590.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 5520259-4 shielded or unshielded?","answer":"The 5520259-4 is unshielded.
