1. Why do we need to integrate magnetic components?
The main purpose of integrated magnetic components is to meet the requirements of Ethernet standards such as 10/100/1000 Base-T and PoE. Magnetic components provide electrical isolation, signal balance and transient protection, while reducing electromagnetic interference (EMI), ensuring the stability of high-speed data transmission.
-
2. What are the main application scenarios of Modular Connectors - Jacks With Magnetics?
These connectors are widely used in Ethernet devices, industrial control systems, network routers, IP cameras, VoIP devices, and scenarios that require high reliability (such as military and aerospace fields).
-
3. What is PoE support? Why is it important?
PoE (Power over Ethernet) allows data and power to be transmitted simultaneously over Ethernet cables, reducing wiring complexity. Modular Connectors - Jacks With Magnetics support PoE and are suitable for devices that require remote power supply (such as IP cameras and VoIP phones).
-
4. Do these connectors support high-reliability (Hi-Rel) applications?
Yes, many Modular Connectors - Jacks With Magnetics are designed for high-reliability scenarios, with EMI/RFI shielding, protective shell and high durability, suitable for military, aerospace and industrial automation.
