02Applications
Where WH56A3188(3)021101 is used
- Switches and routers
- Industrial controllers
- IP cameras and NVRs
- Embedded boards
Typical application
A jack without magnetics passes the signals straight to the cable; the LAN transformer between the PHY and the jack provides isolation and common-mode termination.
Match the jack's tab orientation and LED pins to your enclosure and 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
