Features and Benefits
Modern data systems experience yearly increases in network speeds, requiring jacks capable of handling these data rates without compromising signal integrity. To address these growing needs, the Magnetic jack series provides engineers with an all-in-one solution, combining all magnetic and shielding parts to save PCB space.
But meeting high-speed signal needs is not the only issue faced by engineers, as the ongoing integration of high-speed technologies into new fields requires connectors to withstand harsh environments, including high mechanical vibrations, moisture and dust. With ruggedized materials and design, RJ45 Magnetic Connectors overcome these challenges, ensuring maximum performance in even the worst conditions.
Finally, with increasing data rates and connector density, EMI presents a significant problem for engineers. By employing advanced magnetic shielding and filtering directly into the jacks, Molex offers an exceptional connector solution that enables high speeds with minimal EMI challenges.

Frequently Asked Questions
What is an RJ45 connector with magnetics?
An RJ45 connector with magnetics is an Ethernet interface that integrates magnetic components, including transformers and common-mode chokes directly within the connector housing. These internal components provide signal isolation, noise suppression and impedance matching, all of which are essential for maintaining signal integrity and reliability in high-speed Ethernet networks.
What advantage does integrating magnetics into RJ45 connectors have?
Integrating the magnetics within RJ45 connectors optimizes PCB layout and simplifies system design. This helps to conserve board space, reduce assembly steps and lower manufacturing costs. These connectors also enhance signal performance by minimizing parasitic losses and ensuring precise magnetic coupling for consistent signal integrity across Ethernet links.
Why are magnetics needed in RJ45 connectors?
The magnetic elements used in RJ45 connectors are used to perform four essential roles: signal isolation, noise filtering, impedance matching and surge protection. Signal isolation protects devices from grounding potential differences, while noise filtering suppresses EMI and common-mode noise. Impedance matching maintains signal integrity between different circuits and reduces reflections. Surge protection mitigates voltage spikes and surges.
Are magnetic jacks compatible with all Ethernet standards?
Magnetic jacks are designed to support a wide range of Ethernet standards, including 10BASE-T, 100BASE-TX, and 1000BASE-T, with some designs also extending this to as high as 10G Ethernet. Since not every connector supports every data rate, and because the electrical characteristics, magnetic design and internal construction vary between models, engineers must carefully check product datasheets.
How do I select the right magnetic jack for my application?
Selecting the appropriate magnetic jack depends on a number of factors. An engineer’s first consideration is to ensure that the connector’s magnetics and impedance are rated for the desired data rate. The second consideration is the mechanical and environmental design constraints, such as port count, shield type, PCB footprint, and operating environment. Thirdly, electrical performance requirements, such as voltage isolation, surge protection and EMI or RFI suppression must be matched to the system’s environment. Finally, compliance with standards such as UL and RoHS may be required for regulatory or safety reasons.
Does the reduced profile magnetic jack impact Ethernet performance (insertion loss, return loss, crosstalk)?
No, the connector features an optimized internal layout and controlled impedance to support applicable Ethernet performance requirements and help minimize signal degradation.
Is the low-profile magnetic jack suitable for high-density PCB designs?
Yes. The low-profile design reduces the connector height and enables more compact, higher-density system layouts without compromising RJ45 functionality and Ethernet performance.
