Embedded RJ45 connectors with integrated transformers

Take a look at your PCB. Which component stands out the most? I am sure it is not the huge connector RS3-21001D1A

There are many devices that we connect to Ethernet with standard connector RJ45. And thanks to IoT, the number is increasing. Many times it’s just simple small boxes and if we didn’t have that RJ45 that determines the construction height of the PCB, they would be even smaller. We bring you a simple solution – because brilliant solutions are simple.

RS3-21001D1A is a standard modular jack 8P8C with integrated transformers and two LEDs. But! It is so-called sunk version. You can save at least 3,75mm in comparison with low profile version but even 5,75mm comparing with the standard versions.
