The 0826-1L1T-57-F is a single-port (1x1) 10/100Base-T Fast Ethernet MagJack featuring integrated IEEE 802.3at PoE+ (30W) power delivery capability. Key specifications include a Tab Up (latch up) port orientation, Through-Hole PCB mounting, 1500 Vrms dielectric isolation, an operating temperature of 0°C to +70°C, and integrated Green (Left) / Green-Yellow (Right) LEDs. It incorporates internal magnetics that prevent core saturation under up to 600mA continuous DC current, standardizing power and data connectivity in IP cameras, VoIP hardware, and access control panels.
The 0826-1L1T-57-F is an industry-standard, single-port (1x1) MagJack Integrated Connector Module (ICM) engineered for commercial Ethernet devices requiring high-reliability data transmission and up to 30W of Power over Ethernet (PoE+). Fully compliant with IEEE 802.3 10/100Base-T and IEEE 802.3at Type 2 standards, this connector integrates transmission transformers, common mode chokes, Bob Smith impedance termination, and high-current PoE+ power feed circuits within a standard-height RJ45 housing.
Engineered with a Tab Up (TU) port orientation, the 0826-1L1T-57-F features integrated Green / Green-Yellow (G/GY) diagnostic LEDs to provide immediate port status and link/activity visibility without requiring dedicated light pipes. Its robust copper-alloy outer shield is equipped with Top & Side EMI tabs to guarantee continuous grounding contact to the chassis panel, ensuring compliance with FCC Part 15 Class B emissions. Operating across a 0°C to +70°C temperature range, it is the optimal component for IP security cameras, access control terminals, VoIP phones, and smart IoT gateways.

Inside the 0826-1L1T-57-F, differential pairs for 10/100Base-TX (Pins 1/2 for TX, Pins 3/6 for RX) route through 1:1 isolation transformers and common mode chokes. The center taps of the cable-side transformers connect directly to dedicated PoE+ power rails:
A: While rated for 0°C to +70°C, outdoor installations must account for solar loading and internal heat dissipation from the 30W PoE circuit. If internal enclosure temperatures risk exceeding +70°C, hardware engineers should upgrade to the industrial-grade sibling 0826-1X1T-57-F (-40°C to +85°C).
A: The left LED is a single-colour Green diode (typically 2.1V–2.2V forward drop at 20mA). The right LED is a dual-colour Green/Yellow diode wired in anti-parallel or common-cathode depending on the sub-revision; drive current should be limited to 10mA–20mA via series resistors from the PHY or SoC GPIOs.
A: Conventional magnetics saturate when high DC currents pass through differential windings. The 0826-1L1T-57-F uses high-current center taps with high-saturation ferrite cores tested to maintain ≥350 µH OCL even with an 8mA DC bias superimposed over continuous PoE currents, ensuring zero link drops.
