Frequently Asked Questions
What are the PCB layout and mounting hole requirements for this 1x1 RJ45 MagJack?
This right-angle through-hole RJ45 jack requires a 16.60mm width and 32.60mm depth footprint with a 13.50mm profile height above the PCB. The recommended PCB layout uses a 2.54mm signal pin pitch across 17.78mm and 20.32mm row spans, two 3.15mm (±0.1mm) mechanical mounting holes spaced 12.70mm apart, and two 1.60mm (±0.1mm) EMI shield grounding slots.
Does this RJ45 connector support Gigabit Ethernet and IEEE 802.3af standards?
Yes, the integrated magnetics module is engineered for 100/1000 Base-T Gigabit Ethernet and meets or exceeds IEEE 802.3af standards. It guarantees a minimum Open Circuit Inductance (OCL) of 350uH at 100kHz, 100mV with 8mA DC bias, alongside 1500V AC input-to-output isolation and a built-in 1000pF/2000V DC Bob Smith termination network.
What contact gold plating thicknesses are available for harsh industrial environments?
The copper alloy contacts support selective gold plating in 6u", 15u", 30u", and 50u" thicknesses over nickel. While 6u" and 15u" suit standard commercial networking, 30u" and 50u" gold plating options are recommended for high-reliability industrial applications to maximize corrosion resistance and maintain signal integrity across 800+ mating cycles.
What are the electrical specifications for the integrated LED indicators?
The connector features dual Green LEDs (Left LED on Pins P13/P14 and Right LED on Pins P15/P16) with a dominant wavelength of 560–580nm. Tested at a 20mA forward current (Ta = 25°C), the LEDs operate at a typical forward voltage of 2.1–2.2V (2.5V maximum) with a luminous intensity of 9–25 mcd.
Overview and Application Notes
This 1×1 Single-Port RJ45 Magnetic Modular Jack (MagJack) features an integrated 100/1000 Base-T Ethernet magnetics module engineered for high-speed Gigabit Ethernet and IEEE 802.3af PoE applications. Designed in a right-angle through-hole (DIP) package, it offers a compact 16.60mm width, 32.60mm depth, and 13.50mm profile height above the PCB, complete with a full nickel-plated copper alloy EMI/RFI shield and dual integrated Green/Green LED indicators.

Engineering Specifications & PCB Integration
Designed for wave-soldering through-hole PCB assembly, the connector utilizes a staggered multi-pin footprint with a 2.54mm (100 mil) primary pin pitch, 17.78mm and 20.32mm row spans, and a 12.70mm shield grounding tab span. Mechanical board retention is secured via dual 3.15mm (±0.1mm) mounting posts and 1.60mm (±0.1mm) grounding tab slots. All centerline dimensions are basic and strictly conform to FCC modular interface dimensional tolerances.
