02Applications

Where SYT511Q218AC1A8D057 is used

Switches and routers
Industrial controllers
IP cameras and NVRs
Embedded boards

Typical application

The jack integrates the Ethernet magnetics: the PHY connects to it directly, and the transformer and common-mode termination sit inside the jack.

Check the datasheet for the centre-tap wiring your PHY needs and match the LED pins to the PHY's LED outputs.

Typical application for reference. Follow the PHY vendor's reference design.

Design notes

01Check tab orientation and LED positions against the enclosure opening.Tab Up / Tab Down and LED placement are the most common selection errors for RJ45 jacks.Check my layout →
02Bond the shield to chassis ground according to your grounding scheme.A floating or poorly bonded shield can make radiated emissions worse.EMC troubleshooting →
03For PoE or isolation, the magnetics decide — not the jack.A jack without magnetics provides neither PoE nor isolation by itself; choose a PoE-rated LAN transformer or a jack with integrated PoE magnetics.See LAN transformers →
