Schematic
Contacts 1–8 pass straight through to the cable side (J1–J8); the jack has no magnetics.
Yellow LED on the left (pin 12 to pin 11) and green LED on the right (pin 10 to pin 9); 20 mA, VF 1.8–2.8 V.
From the SYT561188AB1A3DY1027 datasheet (rev. A0).
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

07FAQ
SYT561188AB1A3DY1027 FAQ
Does SYT561188AB1A3DY1027 have integrated magnetics?
No. SYT561188AB1A3DY1027 is an RJ45 jack without magnetics.
Place a LAN transformer between the PHY and the jack, or choose an RJ45 jack with integrated magnetics if board space is tight. Data rate and PoE capability are then set by the transformer.
What does Tab Up mean for SYT561188AB1A3DY1027?
Tab Up describes where the latch sits relative to the PCB.
With Tab Up the latch faces away from the board; with Tab Down it faces the board. Choose the orientation that matches your enclosure opening and LED placement, and check the mirrored pinout before swapping one for the other.
How do I get samples of SYT561188AB1A3DY1027?
Samples are available for evaluation, and selected parts are free of charge. Our FAE team will be glad to confirm the options for your project.
