LPJD0011DNL Vertical RJ45 Connector With 10/100 Magnetic Top Entry
The LINK-PP LPJD0011DNL is a highly reliable Vertical (180° Top Entry) RJ45 Magjack designed for 10/100Base-T Fast Ethernet applications. By integrating the isolation magnetics and common-mode chokes directly into a vertical housing, this connector minimizes PCB footprint and optimizes cable routing in tight or stacked enclosure designs.
Operating within a 0°C to 70°C commercial temperature range, the LPJD0011DNL is fully compliant with IEEE 802.3 standards. It features a robust Bob Smith termination circuit to suppress EMI and is completely LED-free, making it a cost-effective, space-saving solution for SOHO modems, switches, and LAN-on-Motherboard (LOM) applications.

Key Features of 10/100Base-T Top Entry RJ45
1. Vertical Space Optimization (180° Top Entry)
Unlike standard right-angle connectors, the 180-degree vertical orientation allows network cables to be plugged in from the top. This is critical for top-down chassis designs, testing equipment, and dense multi-board configurations.
2. Advanced EMI Suppression (Bob Smith Termination)
The internal schematic features integrated isolation transformers alongside a built-in Bob Smith termination circuit. Unused pins and center taps are terminated with 75Ω resistors and share a 1000pF/2KV high-voltage capacitor connected to the shield ground. This significantly reduces electromagnetic interference (EMI) and prevents signal reflection.
3. High-Reliability Manufacturing
- 1500Vrms HiPot Isolation: Protects downstream PHY transceivers from voltage spikes and static discharge.
- Wave Solder Compatible: The UL94V-0 thermoplastic housing withstands wave soldering peak temperatures of 265°C for up to 5 seconds.
- 6µ" Gold Plating: Ensures stable connectivity and corrosion resistance for standard commercial environments.
Applications of 10/100Base-T Vertical RJ45
The LPJD0011DNL is engineered for standard indoor and commercial networking hardware, including:
-
SOHO Equipment: ADSL/VDSL modems, home routers.
-
Networking: Fast Ethernet Hubs and Switches.
-
Computing: LAN-on-Motherboard (LOM) and embedded PC boards.
