Q&A About LPJK7403B97NL Right Angle RJ45 Connector:
The LPJK7403B97NL is an integrated RJ45 MagJack connector that combines a standard RJ45 interface with built-in LAN transformer components. By integrating magnetics inside the connector housing, PCB space requirements are reduced while maintaining excellent signal performance and electrical isolation.
Compared with discrete Ethernet transformer solutions, an integrated 1000Base-TX RJ45 connector with magnetics simplifies board design, shortens development cycles, and improves overall system reliability.
1. What is the difference between an RJ45 connector and an RJ45 MagJack?
A standard RJ45 connector only provides the physical Ethernet interface, while an RJ45 MagJack integrates the required LAN magnetics inside the connector housing, reducing PCB space and improving EMI performance.
2. Does LPJK7403B97NL support Power over Ethernet (PoE)?
No. The LPJK7403B97NL is a non-PoE Gigabit RJ45 connector designed for standard 1000Base-TX Ethernet applications without integrated PoE capability.
3. What isolation voltage does the LPJK7403B97NL provide?
The connector provides 1500Vrms isolation between the PHY side and line side, meeting IEEE Ethernet isolation requirements.
4. Is this RJ45 connector suitable for industrial applications?
Yes. With an operating temperature range of -40°C to +85°C, the LPJK7403B97NL is suitable for industrial networking equipment and harsh operating environments.
5. Does the connector comply with IEEE 802.3 standards?
Yes. The LPJK7403B97NL fully complies with IEEE 802.3 Gigabit Ethernet specifications and is also RoHS and UL certified.
