Frequently Asked Questions
What are the technical benefits of an integrated transformer and dual LEDs in this RJ45 connector?
Integrating the 100Base-TX isolation transformer directly inside the connector housing eliminates discrete external magnetics on the PCB, shortening critical signal paths and ensuring 1500Vrms IEEE 802.3 isolation. The built-in dual LEDs provide immediate visual diagnostics for Ethernet link and packet traffic without additional light pipes.
What is the recommended PCB footprint and hole layout for this magnetic jack with LEDs?
The footprint requires 8x Ø0.90mm through-holes on a 2.54mm grid (11.43mm span) for signal pins P1–P8, 4x Ø1.02mm holes for LED leads P9–P12, dual Ø1.60mm alignment peg holes, and dual Ø3.25mm ground retention holes spaced 15.75mm apart with a ±0.05mm tolerance.
How do the magnetic and electrical specifications perform under DC bias current?
The internal transformer provides an open circuit inductance (OCL) of at least 350µH at 100 kHz (0.1V) when subjected to an 8mA DC bias current, suppressing noise and preventing signal saturation during standard 10/100Base-TX transmission.
How do the materials and plating ensure signal integrity and corrosion resistance?
Contacts are stamped from phosphor bronze with 6µ" gold on the mating area and 100µ" tin on solder tails over a 50µ" nickel barrier. Encased in a UL 94V-0 PBT housing and a 30µ" nickel-plated copper alloy shield, the assembly ensures continuous 360-degree EMI isolation and reliable contact resistance across 0°C to +70°C.
