1. What are Modular Connectors - Jacks With Magnetics?
Modular Connectors - Jacks With Magnetics are modular connectors with integrated magnetic components, mainly used in high-speed data transmission scenarios such as Ethernet. Magnetic components (such as transformers and filters) are used for signal isolation, impedance matching and anti-electromagnetic interference (EMI), ensuring the stability and reliability of data transmission.
-
2. 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.
-
3. 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).
-
4. How to choose the right Modular Connectors - Jacks With Magnetics?
Factors to consider when choosing:
Number of ports: single-port, multi-port, or stacked configurations.
Speed support: such as 1Gb/s, 10Gb/s, or higher.
Mounting method: panel mount, onboard mount, or through-hole mount.
Shielding performance: whether EMI/RFI shielding is required.
